WOW ........... you got to be KIDDING, eh?
320 X 1, my golden eagle CB watt meter doesn't even read that high! :-)

Mike,
You're putting words in my mouth - I've not said anything about whether
an antenna is "half decent" or not.
What I can tell you for sure is that a 132ft dipole at 50ft above
average ground will have a feedpoint impedance of around 10-j1059 Ohms
at 1.9MHz; and that load will result in 6.5dB loss in 100ft of Wireman
551 if it's dry, and 9dB if it's wet. I leave you to judge whether or
not that constitutes a "half decent" antenna for that band.
Why are the losses so high? Because that feedpoint impedance produces a
VSWR of 320:1 on the 400 Ohm 551 ladderline.
73,
Steve G3TXQ

Okay...
So what I just read from the link you sent, if I take and put up a center
fed Zepp with 66 feet on each side, fed with 450 open line and assume no
loss from the tuner or balun that antenna won't make a even halfway
decent multiband antenna?
Mike
