I prefer to use ohm 18 AWG solid…. For example, at 30 MHz, 20' of RG will show a 1. For that matter, the off center fed types like the Carolina Windom are the same stuff. Long Life and High Reliability We designed this antenna back in and because it spanned the entire 88 - band without a retune, we made it the standard antenna we sold with all. Either type of adjustable circuit would match the tube impedance to a wide range of output impedance requirements. The center-feedpoint is obvious from the position of the feedline. These have obscured or ignored many of the basic facts about OCF operation.
Ham Radio Wire Antennas
Another issue which involves the above problem is, that you will have increased noise levels. Our 8-Band models have a 90 foot leg and a foot leg, totaling feet. They also are under the misconception that changing the feed line to some mysterious secret length, or use another type of feed line these problems will be eliminated. Better in my opinion if fed with 50 or even better 75 ohm coax. I didn't think so. There are reported to be some "magic" lengths that work better then others
Buckmaster OCF Dipole Antenna
You will not get much better performance then the Half wave Dipole Antenna or Loop antenna. It was an easy installation, and the SWR is great on all bands. You make think with your slick tuner that you can get alot of other bands with it, but it will be terribly inefficient on those bands. I tend to doubt that, and since your using a tuner anyway, whats the point?
Buckmaster World wide DX, multi-band, no tuner required, Off-Center-Fed (OCF) Dipole Antennas
Description: It works on 7 different bands with no tuner required, especially the popular 80, 40, and 20M bands. Your RF leaving your wire is looking for a Circuit board to excite, this is most likely going to be in some of your electronics or more likely your neighbors. Balun will be a 4 - 1. Now I just dont think they are worth the time and the increase in gain versus one of the above.
