It’s a long run but no shorts. Using LMR400 with a run 8 feet up the wall, 20 feet across the attic, 8 feet down the outside wall and into a mfg lightning arrestor, then to 50 feet of lmr 400 buried in conduit to my 6btv that had a 1:1 balun before feeding the antenna. I’ve checkEd with an ohm meter and everything is good - no shorts.
Inside I have my 857d to my z-100 to my feed point which goes up the wall to the description above. - Chad > On Oct 16, 2020, at 7:35 PM, Jonathan Guthrie via BVARC <[email protected]> > wrote: > > > Several things.
