Jim, Here are the rules that will determine what you can do on the FLEX-6700 1. You may connect up to 5 antennas 2. Only two of the antennas (ANT1, ANT2) are connected to the PA for 100W out 3. Two antenna ports are receive only (RX A, RX B) 4. The XVTR port can be used as a receive antenna or a T/R antenna, but the output power is only +0dBm nominal 5. All 5 antennas have 144MHz capability, but 144MHz is limited to +0dBm nominal
So if you intend to transmit on the PA with 100W on more than two antennas, then you will need an external antenna switch. Your VHF+ antennas will have to go through transverters/amplifiers/preamp and so this will involve switching of course. I assume you are already doing this external to the FLEX-5000?
