Re: [Repeater-Builder] Re: Double the gain or double the power?

Try a little process of elimination, dummy load the TX before the duplexer and test your output, then re-insert the duplexer and dummy load out of that and compare again, like other people have suggested duplexers on 2m can have high insertion losses, have you checked the patch leads feeding the cans.

If all looks good, then it might be an idea to get some fresh coax (removes the water problem) and invest in a new phasing harness if needed, if finances are a problem then it might be worth just increasing the output power, providing the SWR is ok, a sort of compromise until you can replace whatever in the plant is causing the problem.

I hope you get to the bottom of this.
