Cable run for the packetflux syncpipe is about 6ft if that was your question.

Is it 24V or 29-30V? How long are the cable runs?

We have 2 Aps on the same water tower. Both using CMM for their timing. Both of them also have their Cambium supplied GPS antenna plugged in (emergencies). One AP is running 2.4.3 works fine with GPS antenna plugged in and using CMM for timing. One AP is running 2.6 can’t see satellites because the tank is blocking its view. Is on CMM but will not get timing from CMM no matter what I do. Obviously our next step is to climb the water tank and remove the GPS antenna so it stops confusing itself but it’s too windy today to climb. If I’m using CMM for my timing why does it care about the cambium supplied GPS antenna? It should be disabled when I switch it to CMM. I’ve put 2 new Aps on it with same results. Conclusion: 2.6 is confused by having 2 timing sources even though you choose one. If you’re using CMM for your timing for the love of all things fluffy don’t plug in the Cambium supplied GPS antenna.
