[TowerTalk] Remote balun 4:1 or 1:1 ?

[Steve Forst]

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?
