Satellite antennas tuning device TELEMANN 1600

1

 

TELEMANN 1600 is a compact device facilitating fine tuning of the satellite antenna. A list of transponders for 10 satellites was loaded in its memory (up to 300 preprogrammed transponders overall). When tuning an antenna to the necessary satellite, you can select the corresponding transponder of the given satellite and turn the antenna until it is detected automatically with the device. The device is characterized of high performance, managing the analysis in a matter of seconds. Further, the device allows analyzing the parameters (signal level, BER and CNR) of the selected satellite channel that helps to carry out fine tuning of the antenna. Sound signalling of tuning and a level graphic display mode facilitate the process of satellite search.
