I have four radios one is brand new. I have a brand new Solarcon a 99 antenna and new RG 8X coax. My coax run is 100 feet. My antenna is about 25 feet to the base. I cannot get over 1 mile or so with four watts or 100 watts. I cannot figure this out. My standing wave is excellent. 1.1 on channel 1. Any ideas? I do not know how to diagnose this problem. I have marginal receive.
