I live in the mountains and have a repeater up and running. It is a "home brew" repeater consisting of two 40 watt Motorola GM-300s tacked together with a 50 watt Cellwave duplexer running a 5 MHz split in the VHF band. My question is this, If I were to add a 100 watt amplifier to this system in line between the duplexer and the antenna, will this have a negetive effect on the performance and isolation of the duplexer? If I place the 100 watt amp in line between the TXer and the duplexer, I will have to get a new duplexer as the old one is only rated for 50 watts. Thank you all.
