I have used a 4:1 balun with 450 line. Tuning was OK but not as good as
expected. I have also used LMR400 to directly feed a 160 meter dipole.
This was a great performing antenna except that it was unpopular with the
XYL because with a bit of power the garage door opener and big screen TV
would turn on and off at will. <grin> I plan to put up another dipole like
this in the future with a 1:1 balun at the feedpoint.

Subject: [TowerTalk] Remote balun 4:1 or 1:1 ?
Tried running ladder line into the shack, but too much RFI. Most sellers
of remote baluns offer 4:1 baluns for connection between coax from the
tuner and 450 ohm ladder line to the antenna.
The guys at DX Engineering have a 1:1 balun for this purpose, which they of
course say works better They also say to use 300 ohm line instead of the
450 line.
Who's right?
