[TenTec] OCF Antennas - Which commercial antenna is gest?

[Wade Staggs]

*Hello Rick,*
*                   You have a very good memory! I use the Ugly Balun (
about 12 feet of RG-8 wrapped around a 3 inch PVC Pipe ) this is a Current
Balun. Although we don't like the loss from the Coax. We haven't been able
to justify a proper 1 to 1 Current Balun yet. About 75 feet of 450 ohm
Window Line. The untuned SWR on 75 meters is about 1.7 to 1 and less than 3
to 1 on all but 15 meters. We just wanted to complement you on your
excellent memory. *

Wade/KJ4WS*
