Darrell:
I just ran an old one I had in EZnec.
The 2:1 SWR bandwidth is about 280 Khz.

I remember an old article by L B Cebik that described a way you can
broadband an
80 meter antenna simply by using a couple specific lengths in series of 75
ohm and
50 ohm feedline. If you are interested I can try to dig it up and send you
a copy.
