I'll try to make this as detailed and as short as I can. My current set-up in the shack is two external/outside antennas. One for the repeater and one for base. The first antenna is an Ed Fong DBJ-UHF GMRS w/ 50' Messi & Paoloni (M&P) coax about 43' above elevation. It's my repeater antenna. The repeater is an all-in-one unit with the duplexer (Bridgecom BCR-40DU), it has two 40w radios inside. Second antenna is a Comet CA-712 EFC w/ 25' of M&P coax about 20' above elevation....this is for a KG-1000G+(50w) base unit. I understand that duplexers take at least half of the power away. Got it.....nothing I can do about that. I ran a test with a SureCom SW-102. Correct, this is not a "high-end" tester. I do this for a hobby. Here's what I got.
I understand that I've opened myself up to a lot of criticism because there's tons and tons of HAMS here. Also. I've left a lot of variables out, I may not have given out every minor detail. I know. So please, if you're one of those people, please try to reframe. I just need opinions/advice. Which one would you put the repeater on and which one for base? Thanks WRXU693

RPT-SWR-DL(Dummy Load) = 1.01 w/ 22.3watts
RPT-SWR-Coax(50')-Ed Fong= 2.8 w/ 17.7watts
RPT-SWR-Coax(25')-Comet 1.2 w/ 22watts
Base-SWR-DL 1.1 w/ 46.7watts
Base-SWR-Coax(50') Ed Fong 2.0 w/44.6watts
Base-SWR-Coax(25') Comet 1.6 w/ 44.5watts
