Which one would you choose?


Question

Posted

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.

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

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

I’m easily confused. You already said which antenna setup is for which radio in paragraphs 2 and 3, so what exactly are you asking?

HS.......I just explained the Comet is at the lower elevation but better swr. That's why I'm asking the question. Hey shannon, I know you mean well but you don't always need to be the first one to answer questions on this forum. I don't know if you do it because you're a moderator, a showboat, a HAM or just answering most post just for the sake of earning badges. But I just explained what I know, then ask a reasonable question.    

I gave an honest answer. I’m not sure what about my response bothered you but it’s an easy situation to rectify.

Congrats. You've placed yourself in the pile of users that no one wants to help.

Have you swept your antennae to determine what they are resonating at?

...or maybe @Sshannon was just trying to help someone out solely for the satisfaction of helping them. Unfortunately "some people" have no gratitude.

"Which one would you put the repeater on and which one for base?" Translated....

Which antenna...smh....would you use based on the limited information given for each set-up?

I would use the Comet antenna at the higher elevation for the repeater.
