I agree with Dave (K4JRB)
REMOTE BALUN is the way to go...I wound my own and it covers from 160m -20m.
I'm sure there are a few db in losses and I could care less. I'm feeding a
dipole and don't need every possible available db. The antenna has gain as I go
up in frequency I usually end up using the attenuator since signals on these
low bands are so strong.
I wound my balun with #12 stranded teflon coated silver wire and running 1KW
RTTY I can detect no heating of the balun.
In addition I have installed a Radio Works isolator after the balun since there
is some SWR on the coax from the balun to the tuner. I'm very satisfied with
the results of this installation.
In the country I have open fed dipoles where the feedline come directly into the
operating position. I haven't experienced the RFI mentioned in other email.
Perhaps it's because the led length is over 60ft. In the past when I had RFI
from the open wire feeder I simply added some lenth to the feedline and the RFI
