Filter allocations for each of the UHF inputs can be determined using jumpers (options 0/4, 1/3,2/2 are possible). In addition, the amplifier connects all inputs on the principle of an antenna crossover, so it is ready to sum signals from various antennas, including the readiness to receive MUX in the VHF band. In addition, at the UHF1 input, the WK-410 has a built-in filter, made in SAW technology, which eliminates the adverse impact of interference from mobile Internet (LTE) signals.
The basic task of the amplifier is to select four signals of different levels received in the UHF band in order to equalize them. The signals prepared in this way can be directly connected to a TV set or DVB-T tuner. In the case of a larger cable installation, the signals from the WK-410 can be amplified using an external WSS or WMX amplifier and then sent to the reception points via cable installation. Adjustment of the signal gain level for each of the four amplifier paths is carried out using potentiometers.
Thanks to the use of a plastic, splash-proof housing, the WK-410 can be mounted outdoors, directly on the antenna mast.
