I am going to go and measure again, but assuming I measured wrong
before, Is a 100 foot run too long for the antenna to work properly?
It's the loss, not the length. LMR600 has only 0.781db loss/100 feet,
perfectly acceptable.
I am probabaly going to use 300 ohm twin lead for the lead in, unless
people think it should really be coax.
If you want the least loss (within practical limits - you *don't* want
3" dry nitrogen rigid cable) use ladder line, but the tuner will be a
bit much. Even LMR200 is less than 2db loss/100 feet, and RG8 (not
8X) is a hair over 2db.
