You have 2 Decoders, and the concept is to pair the 2 decoders to get heartbeat signal through the usage of diplexer. Every diplexer have two ports, ( antenna & Satellite) and the receiving port . With this setup you’ll need a dual LNB.
* Connect two separate cables from the dual LNB unto the receiving ports of the primary and secondary diplexers.
The next step is to connect cables from the Satellite side of the diplexers unto each decoder respectively. After getting the signal quality on each decoder, the next thing is to connect the heartbeat cable.
* Connect a cable from the primary diplexer antenna port unto the secondary diplexer antenna port.
