Antenna Amplifiers: No More Pixelation – Stable Power for Your RTV Signal
Do you have a weak picture that "pixelates" or loses strength on a second TV? This is a natural problem in any installation, because the signal always loses power as it travels through cables and passes through passive components such as splitters or sockets. A signal amplifier compensates for these losses by raising the signal level to the value required by tuners. These devices are essential for stabilizing reception, guaranteeing a crystal-clear picture on every connected TV.
Standard Amplifiers – Signal Optimization and Loss Compensation
In this section you will find devices that are essential for optimizing the signal directly in a home installation:
-
Amplifiers, antenna combiners: These are the devices you need when the signal is already weak or has to be distributed to several TVs. An antenna amplifier increases signal strength, while a combiner enables signal combining from different antennas (e.g. terrestrial DVB-T and FM/DAB+ radio). These are basic tools for single-family home installations.
-
Multi-band amplifiers: These are advanced devices that allow independent gain adjustment in individual bands (e.g. VHF and UHF). They are ideal in situations where different multiplexes (MUXes) have very different signal strengths, ensuring equalization at the output.
Power Supply and Protection – Clean Signal Without Interference
The proper operation of active devices (antennas with amplifiers, amplifiers) and the elimination of interference are the task of these specialized products:
-
Antenna power supplies and power separators are essential for powering active terrestrial antennas and amplifiers that require voltage to operate properly. This is a key element of any active installation.
-
LTE 4G / 5G anti-interference filters: You must use them if the TV picture is disturbed, cuts out, or "pixels" appear on it. These filters effectively eliminate strong interference from mobile phone transmitters (4G and 5G networks), which operate on frequencies close to DVB-T, restoring clean and stable reception.

Distribution Amplifiers – Power for Shared Installations
If you own a hotel, guesthouse, or manage a multi-family building, you need equipment for professional signal distribution:
-
Broadband amplifiers and distribution amplifiers: These are high-performance devices designed for use in shared installations, where the signal must be distributed to many subscriber outlets over long cable runs. Distribution amplifiers guarantee that the final signal power will be appropriate for every receiver, regardless of the distance from the amplifier. Broadband amplifiers, in turn, are capable of simultaneously amplifying the entire band (e.g. FM, DAB+, DVB-T), which simplifies configuration. Their use is crucial for maintaining high signal quality at all branch levels.
