Diplexers, Triplexers, and Combiners
Diplexers
and Triplexers
LBA Technology custom engineered diplexors and triplexors provide
broadcasters the ability to transmit two or three different AM signals
for one series-fed antenna.
Diplexors include an antenna tuning unit and rejection filter section for each
frequency.
Triplexors include an antenna tuning unit for each frequency and two rejection filter sections for each frequency.
Traditionally, these systems are fabricated in a single, multi-compartment cabinet. Each system is designed for the specific frequencies, transmitter output powers and antenna base impedance. Consult the factory of local LBA Technology representative for more information.

Transmitter Combiners
Permitting the operation of
two or more same frequency transmitters at the same time, these
combiners allow broadcasters to achieve increased power and fail-safe
operation.

"I'd like to tell you how pleased we were with your diplexer for WJTI 1460. It arrived yesterday, we took it to the transmitter site and decided to place it in the position of the existing T network. We came back later and installed it, and everyone noted how well the box was constructed. John, the station owner, said it was all pre-tuned, and so we tried it, even though we didn't bring along an impedance bridge, and it worked great! Both transmitters displayed no indications of the other being there..." |
