Rune, Back in 1997 N6BV and I did some testing using "ladder line" (not the real 600 ohm stuff) and some 9:1 baluns on each end. We were looking at a site in YV where the beach was about 1000' from t

I suspect few here would consider 2dB negligible. i don't. N6BT says 2dB is a lot. It's because ladder line is used at 450 or 600 ohm impedance, so it of course has one tenth the resistive losses of

Exactly right -- it's because the current is much smaller for the same power. Correct Jim. With an RF amp meter 5.477 amps squared times 50 ohm coax equals 1499.8764 watts With 1.8 amps squared times
