I am acquiring two used GAP verticals, a Titan and a Challenger. I have asked GAP if they may be adjusted to work directly with 75 ohm CATV cable, or through a balun, here is their less-than-helpful
David, I mailed out the reviews today. If you can't wait, you can view the QST review of the Challenger from the Members Only Product Review on the ARRL web site. BTW, I have no connections to GAP An
Use an unun not a balun if you're simply going from 50-Ohm antenna or coax to 75-Ohm coax. Personalyy, why bother? 75 to 50 is a 1.5:1 VSWR. You'll probably lose the same in a tuner or unun. I fed a
See my reply on the CATV line! The SWR on the 75 ohm line might be 1.5:1, but the SWR presented to a 50 ohm system at the end of the 75 ohm line can be the square of the mismatch at the input end of
