My SWR’s are registering 3+ and I’ve changed antennas twice with direct connection/ connectors using N adapters. I’m using LMR 400 coaxial (50 foot) run. The power coming out of the radio is 8 watts via dummy load/meter. The antenna is from M2 and requires no tuning. \n\nNot sure what else I can do?\n\nSloan (KN4GQB\n_______________________________________________\nSent via [email protected].
