[Elecraft] A/B antenna switch for ladder line fed antennas

I use DPDT relays here to switch my 450 ohm feedlines.
Works very well.

Subject: [Elecraft] A/B antenna switch for ladder line fed antennas


I have a fancy switch for A/B antenna testing for coaxially fed antennas 
but do not know what folks use for antenna switches with antennas fed by 
ladder lines.  I want to compare a 160 meter full wave loop fed with 
homebrew ladder line to a G5RV fed by 450 window line.  Any suggestions?  
I knife switch of some sort like we used in grade school science labs in 
the '60s?  Or is there something more modern?
