Thanks, W1VT for the reply and info.
Balun for Doublet Antenna N8EUI on 4/3/19
Hello,
I'm building a 40-10 meter doublet for summer field day. I will be feeding it with 450 ohm window line. My antenna tuner only accepts unbalanced feedlines, so I will need a coax to twin lead balun to transition from the 50 ohm tuner to the 450 ohm feed line. My question is what ratio of balun should I use? Conventional wisdom would say a 9:1 balun. Is this correct? Also, should a current or voltage balun be used in this antenna design?

Thank you,
Tom, N8EUI
