The F-9999999 antenna amplifier is designed to amplify a weak signal of terrestrial television in DVB-T, DVB-T2 and analog TV formats. It is most often used in places with unstable reception, a long distance to the TV tower or when the signal is significantly weakened due to a long cable, splitters or dense construction.
The amplifier is installed directly in the antenna box instead of the standard matching board, so amplification occurs at the antenna input. This is especially important with a weak signal level - when the TV or T2 tuner periodically "spills" the picture, freezes or does not find some channels at all.
The F-9999999 model has proven itself well with Polish "lattice" type antennas, as well as with many indoor and outdoor decimeter antennas. In practice, the amplifier often helps where ordinary cheap boards work unstable or make a lot of noise.

Unlike many cheap analogues, the amplifier is made on a high-quality fiberglass board, which has a positive effect on the stability of operation and durability. Due to the low noise level, it does not just "raise" the signal, but makes the reception more stable and clean.
Original F-9999999 amplifiers are available in the WST store. This is a proven solution for improving digital television reception in difficult signal conditions.
