The Yota operator provides its subscribers only with wireless Internet. This is where most of the user difficulties arise. If wired technology makes it possible to achieve constant high speed and stability (exceptions include only accidents at stations), then wireless network influenced by many factors.

Let's figure out whether an antenna is needed for Yota, and how it can affect the speed and stability of the connection.

External antenna amplifier for Yota LTE modem: necessary or not?

To understand this question, you need to evaluate the characteristics of the Internet at different points in time. If the network remains stable and the speed does not drop, then the gain additional devices not required. But in what cases is it worth getting an amplifier?

Consider purchasing an amplifier or self-production in the following situations:

• constant loss of signal at different points in the house;
• speed changes;
• using a large number of devices connected to the Internet through one router/modem.

Users have a choice: buy branded equipment, or try to amplify the signal with their own hands. Let's talk about each method in more detail.

Amplifier options

If your task is to provide Internet a large number of devices, then the Yota b315 Internet center with an external antenna is suitable for you. The device itself allows through Wi-Fi network, and a connected external amplifier will increase the stability and signal reception.

On the official website you can purchase yota b315 for 6,900 rubles (cost in Moscow and the region). If you do not need an Internet center, then you can get by with a connector for an external antenna - LU150 LiTE. You can connect an external antenna to the Yota modem only if there is a special port or USB connector.

Before purchasing, carefully study the characteristics of one and the second device - the presence of ports must match. The device is connected to the modem through a pigtail - an adapter from a standard antenna socket to a specific connector.
If it is not sufficiently developed, and the modem constantly switches to 3G, then this point must also be taken into account when choosing an antenna. The device must support both technologies. Otherwise you will have to buy two antennas.

Do-it-yourself signal amplification

External antennas for the Yota modem and 4g lte signal amplifiers cost a lot of money. Most users cannot afford to purchase expensive devices. However, you shouldn’t despair in such a situation - you can try to make an antenna for Yota with your own hands.

You can make an amplifier from available materials. The most common example is a saucepan, an aluminum basin, or foil. The modem is placed inside a pan or cardboard box covered with foil. Next, the structure is attached to the place where the signal reception is higher. If you are going to mount your homemade structure outdoors, then take care to protect the modem from external influences (rain, frost, and so on).

A regular satellite dish can also be used to boost the signal. You must attach the router to the converter, then point the structure in the direction of good signal reception. If you don’t have either one or the other, then use copper wire and foil PCB to create a Kharchenko antenna. More detailed instructions and you can freely download the diagram for it from the Internet. With the help of our tips, you can do without spending a lot on amplifiers.

There are situations when the Internet speed does not meet the needs of customers. In this case, it’s worth thinking about how to strengthen the Yota signal. But before you think about whether you need an amplifier Yota signal in one way or another You should first pay attention to the following factors:

• presence of obstacles in the room;
• station distance;
• weather;
• network stability;
• speed changes;
• number of devices used.

If none of the above appears, then nothing needs to be strengthened. Otherwise, you need to decide how to amplify the signal. Basically, an amplifier is required for the lu150 4G modem.

If the Yota signal level is low, you need to use an external antenna, which will help increase the modem signal and make it more stable. To increase the Yota signal level in an effective way the use of antennas is considered. But there are situations when it is enough to place the connected Yota modem on the street.

You can buy an amplifier at a communication store. Branded equipment for these purposes costs a lot of money and subscribers do not always have this amount available. If it is not possible to purchase an amplifier, you can make it yourself. Moreover, this can be done using improvised means. Do-it-yourself Yota signal amplification is much more effective than something purchased in a store.

Do-it-yourself signal amplification

A do-it-yourself antenna for Yota can be made from the following items:

• pots;
• aluminum basin;
• foil;
• beer can.

Before you begin directly creating an amplifier, you need to prepare the following tools:

• Screwdriver Set;
• soldering iron;
• glue gun

In order for an external antenna for a modem from Yota to live up to expectations, its construction requires a high-frequency antenna cable, copper wire, and a plastic pipe. Another important point worth knowing is the broadcast frequency and a diagram of how to connect the antenna to the Yota modem. There is a lot of information on how to connect an antenna directly to a device on the Internet.

The most effective is considered to be a self-made antenna for LTE Yota from Kharchenko. It is a figure eight made of copper wire that needs to be attached to the reflector. When making a figure eight, you need to strictly maintain its dimensions. The only drawback is that in this case you will need to connect the cable to the connector located on the case. If there is no such connector, you will need to solder the cable to the internal board. As for the advantages, your signal amplifier for the Yota modem can be placed at a high altitude, which will help enhance signal reception even more.

The Yota antenna can also be made from an old unnecessary pan with a capacity of about three liters. In addition, an aluminum basin or a cardboard box, which must first be covered with foil, may be suitable. The modem is located in the center. If necessary, you can change the orientation of the Yota 4G modem inside the reflector to the desired values. In this case, there is no need to solder. The device is attached with a glue gun or improvised materials.

Another option for designing an amplifier is to use an aluminum can. It requires cutting off the top and making a side cut 40 cm from the bottom. Place the modem in it and connect an external antenna to the computer. To check the indicators, you need to go to the page located at 10.0.0.1. and perform testing.

Now you know how to strengthen the signal of a 4g modem and you can easily and quickly use one of the methods described above to get maximum Internet connection speed from Iota.

Good afternoon. People living in a private house often face the problem of lack of high-quality Internet. ADSL is rarely used today, and the speed leaves much to be desired. It is especially problematic if the house is new and there is no telephone, then you will have to pull the wire for the sake of not very fast Internet. And even if there is a telephone, it is not a fact that the line laid a long time ago will be suitable for the Internet. Fiber optics are expensive. Some add up with neighbors and then the costs may become acceptable. However, not everyone needs good internet. Remains Mobile Internet. 4G technology allows you to reach a maximum of 150 Mbit/s, but for such a speed you need high-quality signal reception. The built-in antenna (or rather two) of the modem is not always enough for this. So, today we will make a Kharchenko antenna for the Yota 4G modem. YOTA 4G LTE WLTUBQ-108 modems are currently available for sale.

We have to:
- YOTA 4G LTE WLTUBQ-108
- Copper wire with a cross section of 2.5 mm
- Sheet of iron
- Coaxial wire with a resistance of 75 Ohms, thin
- Double pigtail from MS156 to SMA Female
- SMA Male connector
- Drill
- Drill 3 mm
- Plastic tube or any dielectric
- Soldering iron
- Solder, rosin
- Hot-melt adhesive
- Clamps
- USB extension cable

Step 1 Prepare the modem.
Before you start making the antenna, you should connect the modem to the computer. Go to the modem settings at 10.0.0.1 and write down the SINR/RSRP values. This should be done to compare the change in signal level after connecting the antenna. The modem is quite easy to disassemble. You need to use something sharp, for example an awl or a knife, to pry and remove the top cover. This must be done very carefully, since there is a built-in antenna under the cover. The main thing is not to damage it. Removing the cover:

And on the reverse side it looks like this:

Our modem supports MIMO technology. MIMO (Multiple Input Multiple Output, multiple inputs, multiple outputs) is a spatial signal encoding technology that allows you to increase the channel bandwidth. When using this technology, two or more antennas are used for data transmission and the same number of antennas for reception. In our case we have two antennas. Each antenna has its own socket:

One socket is located at the top of the modem, the second is on the right side. It is not good to leave the modem open, so placing the case on the modem, measure the locations of the holes for the sockets and drill with a drill with a diameter of 3 mm:

It is quite difficult to become extinct. After drilling the holes, put the case on the modem and see if the holes match the sockets. If necessary, enlarge the holes with a knife in the desired direction. After making sure that the holes coincide with the sockets, put on the case and close the top cover.

We will connect the antenna to specially prepared sockets. For this we need an adapter. On one side, there will be two MS156 connectors (we connect one antenna to two sockets), on the other side there will be a high-frequency SMA Female connector. You can order it on aliexpress or buy it in a radio parts store:

Connect the pigtail to the modem:

At this point, we put the modem aside for a while.

Step 2 Antenna calculation.
There are a lot of antenna options. In my opinion, the most effective and easiest to manufacture is the Kharchenko Antenna. It is named after the engineer who developed and described the design of this antenna - Kharchenko K.P. We will make the antenna vibrator from copper wire with a cross section of 2.5 mm. You can use a wire with a cross section of 2 mm. The wire is easy to buy at an electrician. Before making the antenna, the insulation of the wire should be removed. The vibrator consists of two squares connected at one of their vertices and with the sides separated. The antenna wire is soldered at the connection points of the squares. The antenna input impedance is close to 50 ohms. I chose 75 ohm cable, although it also works well with 50 ohm coaxial cable. The length of the sides of the squares is λ/4, where λ is the wavelength. In our case it is 115 mm. We make a vibrator according to the following scheme:

Where:
Center frequency f: 2600 MHz
Antenna characteristic impedance ρ: 50 Ohm
Wavelength λ: 115mm
Size L1 (outside square): 28.9 mm
Size L2 (inner side of square): 27.6 mm
Size L3 (total frame length): 81 mm
Size L4 (frame width): 40.5 mm
Size L5 (gap at connection point): 1.7 mm
Vibrator-reflector distance D: 13.2 mm
Dimension B (reflector width): 115 mm
Dimension H (reflector length): 115 mm
Vibrator wire diameter: 2.5mm
Total wire length (with allowance for turns): 237.9 mm

Step 3 Assemble the antenna.
Solder the wire to the vibrator. In the end it should look like this:

The reflector can be made from almost any metal sheet. It is also possible to manufacture a mesh reflector. I chose and recommend that you make it from metal from an old system unit computer. The thickness is sufficient and the coating helps a lot. Cut out a square with a side of 115 mm. You can cut more, I indicate the minimum required side of the square. We make a 6 mm hole in the center. In the corner of the reflector we also make a 6 mm hole for mounting the antenna. Then we take a small plastic tube or a tube made of any dielectric. We cut off 13 mm from it and, using hot glue, attach the resulting part in the center of the reflector, so that the holes of the reflector and the tube coincide:

We pass the wire with the soldered vibrator into the central hole of the reflector. Use hot glue to fix the vibrator. Before installation, think carefully about the installation location. The antenna must be positioned so that the vibrator is horizontal. It also needs to be turned with a vibrator towards the receiving tower. It is better to place the antenna indoors. If you plan to use it outside, you should take care of waterproofing the antenna. I mounted the antenna on the window slope on the street. To ensure that as little rain and snow as possible falls on it, I secured it in the upper part. Thus, it is, as it were, under the visor:

Don't forget to drill a hole in the window frame and thread the wire through it.

Step 4 Connect the antenna to the modem.
We install an SMA Male connector at the end of the wire. The middle contact must be soldered, the outer braid is fixed with a metal tube, and insulated with heat shrink or electrical tape.

A network of base stations that expand the coverage area of ​​operators mobile communications, is growing. The signal quality improves and the connection speed increases. But not in all places it is possible to enjoy super-fast 4g LTE Internet, even by purchasing a Yota 4g modem.

Reasons for a weak signal:

• network overload by users;
• significant distance from the base station (typical for small towns and villages);
• the place where the modem is located: height, material and thickness of the walls;
• nearby interference in the form of multi-story buildings, forests, electromagnetic fields from high-voltage power lines.

You can solve the problem of amplifying the 4g signal by installing an antenna for the Yota modem.

Types of antennas and advantages of their use

The Yota operator specializes in providing Internet using high-speed 4g networks. The company sells, in addition to the Yota 4g modem, various modifications of the router and antennas.

Types of industrial antennas:

1. Directional panel 4g antenna. It has the function of automatically switching to a 3g signal if there is no 4g network. There are modifications for operation in two frequency ranges;
2. Parabolic. 4g antenna with maximum gain. It is good to use when the base station is located at long distances. Can be used where there is no signal at all. Disadvantage: high cost;
3. Circular omnidirectional. It is mobile, has a magnetic base and can be installed in different places, including in a car. It does not have a high amplification power and is used in areas with unstable signal reception;
4. Internet signal boosters - indoor antennas. Connect to the modem using a USB cable.

Important! There are antennas for Yota with built-in modems and routers. If you need to boost the signal on an existing device, you need to buy antennas without a 4g modem.

If you don’t yet have a modem, then purchasing a combined device will be cheaper than purchasing the elements separately.

The Yota antenna provides an increase in Internet speed up to 10 times. Installation of equipment and its configuration will be possible for any user who does not have special knowledge.

Homemade amplifiers

If the subscriber is technically prepared, then he can make an antenna for Yota with his own hands. At the first stage, the location of the nearest transmitting center is determined and it is found out whether there is a lot of interference in the line of sight zone. Sometimes connection is impossible even with the most efficient amplifiers. In large cities, a tower located hundreds of meters from your place of residence can provide the same quality of 4g signal as in a rural area at a distance of 10-12 km. This is due to different network loads.

You need to contact Yota customer service for the necessary information about the nearest tower. They can also give advice on how to correctly position the external amplifier. Other options for searching for data are a forum on the provider’s website, third-party Internet resources.

Antenna for Yota using an aluminum can

The can design of the amplifier for Iota is simple, but it will not provide an increase in Internet speed and stability in conditions where the signal is too weak. However, such an external antenna can add the missing stability to the LTE connection. For indoor use only.

A hole in the shape of an Iota modem is drilled in the side surface of an empty can of beer or other drinks. The distance to the center of the hole being made from the bottom surface of the can is calculated using a special calculator for such homemade structures. It can be found on the Internet. It is necessary that the transmitting center sends the signal to the amplifier with the least interference. By changing the depth of the modem and carefully turning the can towards the tower, you can configure the manufactured antenna to receive the signal. The Yota website monitors your Internet connection speed and ping. The modem with antenna is connected to the computer via a USB extension cable.

The design resembles a can antenna, but with a larger reflector area. The reflector can be a cardboard box with a foil-covered surface, a stainless steel pan, an aluminum bowl, a metal grill, etc. The Yota modem is secured inside the container using screws installed in holes drilled on the side, or using other devices.

The pseudosatellite can be mounted outside the building, while protecting the modem with plastic film or a plastic tube. If you correctly orient the homemade design, the 4g signal will be significantly enhanced.

Important! Based on the practice of manufacturing a pseudosatellite, the modem must be placed perpendicular to the ground, parallel to the surface of the reflector.

Experienced users note the reliability and simplicity of the Kharchenko antenna - a thick copper wire bent in the shape of a figure eight. All dimensions indicated on the Internet for this design must be strictly observed. The wire is fixed on top of the reflector, which can be an aluminum plate. The wire is insulated from the reflector. The antenna is tuned to the frequency of its operator.

The structure is installed outdoors. You need to know where the transmitting centers are in order to direct it to one of them, if possible, avoiding interference. It is possible to obtain powerful signal amplification by placing the amplifier at a sufficient height.

Important! The cable from the antenna must be connected to the modem through a connector, which may not be there. Then the modem is disassembled and soldered directly on the printed circuit board.

Using a satellite dish

A television satellite dish is a good solution for obtaining a stable Internet connection in problem areas. The eta modem is placed in a small plastic container (a tube or a yogurt bottle) and secured at the focal point of the dish, where the TV signal converter is usually located. The connection to the computer is provided by a USB cable. The process of setting up the antenna is more complicated.

Points to consider when setting up a parabolic antenna for Internet reception:

1. Unlike tuning to a television satellite, the dish for the LTE signal is directed lower. This is due to the curvature of the reflection;
2. For precise tuning, tracking is performed while the antenna is slowly rotating. computer program Yota changes the quality of your Internet connection. The directional dish must be fixed at the point of best signal reception;
3. After fixing the external antenna, you can try changing the focus location and see how the 4g signal changes. The Yota modem must be installed so that the USB port is located at the opposite end from the dish;
4. If the 4g signal remains unstable, you need to raise the structure higher. A larger plate diameter will also enhance the signal. Satellite antenna meter diameter can guarantee high-quality connection at a distance of 8-10 km from the tower;
5. Simultaneous use satellite dish to receive a television signal and improve the quality of the Internet connection is not possible.

A directional antenna with a parabolic shaped mesh reflector will give the best gain. But it is difficult to find such a structural element for making an antenna; they are not produced by industry due to outdated standards. Although there are ready-made structures of this type on sale.

Strengthening the LTE signal is possible both using industrial antennas and those made by yourself. Homemade antenna requires the presence of certain knowledge and skills. If the user does not have them, the modem may be damaged. In this case, it is better to purchase factory copies in accordance with existing conditions.
