The TD-522 is a combiner to be assembled in a rack cabinet of 19 inches and 1U height. It is an instrument designed to combine different RF (COFDM) signals in DVB-T format. The system provides 46 dBm amplification and an output power of 130 dBµV (+22 dBm) which allows offair distribution in reduced areas.

The TD-522 can combine up to 4 RF input signals from different sources, such as DTT signals, CCTVs, modulators and more, distributing the combined RF output signal through the distribution network.

This is a solution of higher quality than those often used by Z connections, due to it preserves the original quality better and maintains lower noise levels.
