Subscriber amplifiers
Subscriber amplifiers AE-108STm+ , AD 420 Plus DC are designed specifically for the convenience of DVB-T2 reception. The amplifiers are characterized by the feature that they have the ability to supply power to mast amplifiers with a voltage of +12 V. Often in practice this function is very important ( especially for DVB-T2 reception ).
In most cases, it is sufficient to use only one subscriber amplifier (i.e. without a mast amplifier). The optimal gain at a sufficiently high output level guarantees the absence of any distortion, and the small dimensions with ease of mounting have ensured high popularity as subscriber amplifiers. They are usually installed near a 220 V/50 Hz power outlet, located as close as possible to the antenna (from the cable outlet).

Terra HS004
Rating: 4.9
A very expensive amplifier. Its high cost is due to the fact that it is designed to amplify a wide variety of frequencies. The reliable cast housing also played a role in increasing the price tag. It is almost impossible to disable the Terra HS004 - it even has protection against voltage surges.
This amplifier is mainly used by owners of walkie-talkies. This is evidenced by the ability to work with the VHF and UHF bands. I'm glad that this model can split these ranges, allowing you to separately adjust the gain of each of them. To be precise, the device has access to frequencies from 47 to 862 MHz. The gain is adjustable from 34 to 44 dB. At the same time, a specialist will not be surprised that the VHF range is subject to greater amplification than UHF.
Power for this model is provided by an ordinary plug that is inserted into a socket. Therefore, the miniature power supply is located inside the device itself - this is good news. As for noise, its level does not even reach six decibels.
The amplifier is capable of operating at a variety of temperatures - even at 20 degrees below zero. However, there is no moisture protection as such. On the contrary, the case has a large number of ventilation holes, thanks to which the device hardly heats up. It turns out that placing the amplifier outside the room is not recommended.
A nice bonus is the presence of lugs here, thanks to which the Terra HS004 can be mounted somewhere on the wall with ordinary screws or bolts. In short, this is an excellent copy for some special services and other organizations that regularly face the need to improve the quality of signal reception in the VHF and UHF bands. However, digital television broadcasts in the same ranges, so the amplifier works with it too. But does it make sense to buy such an expensive device to amplify an indoor antenna?
We draw your attention to the existence of a model under the index Terra HS004L. It differs from its analogue only in the presence of an LTE signal suppression filter.
Advantages
- Can be mounted on a wall or any other surface;
- Division into subranges;
- There is a version with an LTE signal suppression filter;
- Possible power supply via RF input;
- There is protection;
- There is a DC overload indicator;
- There is a test connector at the output;
- Excellent die-cast housing;
- High gain;
- A large number of connection points can be implemented.
Flaws
- Very high cost.

House amplifier AE-210
| Price: 47 € |
If you need to distribute the signal to more than 3 TVs, then it is better to install a home amplifier. At a relatively low cost, this amplifier has both gain and equalization controls (to equalize signal amplitudes across all TVs). The power consumption of the amplifier does not exceed 10 W with dimensions of 220x110x60 mm
How to connect an antenna signal amplifier
Such amplifiers must be installed in close proximity to the antenna, or at least no further than 3 meters from it if the antenna is external. This is done in order to avoid amplification of noise occurring in the cable.
If you have an indoor UHF antenna, the amplifier can be installed right next to the TV.
You can connect the amplifier to the antenna using special F connectors. They are screwed onto the ends of the cut cable, and a t2 signal amplifier is connected to them.
In the case of an indoor antenna, it is better to purchase half a meter of cable, then connect it to the TV through plugs and connectors. Amplifiers combined with a USSh-1A indoor power supply are also available for sale.
This device should not be installed together with an active antenna.
