| 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 |
