I helped install a new Diamond X-200 dual bander for a friend yesterday. It sits on a 20 foot mast, clear of any nearby obstructions attached to a one story house. There is a short run of new LMR400 coax from the mast through the wall of the shack. New connectors were used and checked for continuity.
When we checked SWR at 5 Watts on 2M, we got above 2:1 across the band... nothing under.
When we checked SWR on UHF it was a near-perfect 1:1. There appear to be no provisions for tuning other than cut or add material. What thd heck js going on???
