Using #10 bare wire is fine. If that's what you have on hand to use (free of incremental cost), then by all means use it. It certainly will NOT hurt anything. There are physical reasons for "bare" an

Hi Paul, Modeling the effect of the feedline and the receiver terminating the feedline is tricky. Some are able to short or open the TX feedline in the shack due to a "favorable" length from the ante

If that were not enough, W8JI famously had a 160 dipole up 270 feet doing A/B tests vs. his verticals, this for over a year I think. In the end, he heard better signals on the dipole just a handful o

This comment applies only to a counterpoise which is a good to excellent ground radial field for 160, and resonant L's. It does not apply to L's over FCP's or elevated radials resonant on 160. To mak

Hi Art, Don't know whether you are measuring L to FCP with nothing else connected or measuring shack side of isolation transformer. You should be measuring on shack side of transformer, with L and FC

Hi Wes, The issue here is that he is not over resonant radials and a balun which would likely call for what you suggest. He's over an FCP roughly 130 ohms capacitive reactance and a true transformer

The business of avoiding high angle radiation at all costs is a real urban myth on 160. NVIS closing of close-in skip zones on 160 can save your run frequency in contests. While creating an R=50, X=

Hi Art. Short answer: Just do it. Go have some fun. SWR does not correlate with performance unless it keeps your transmit stuff from developing output or blows it up. Get your Sark fixed. Let us know

Yup, and some very large percentage of your power is now being dissipated in the ground. Could be as bad as 80 or 90 percent, depending on how low the actual radiation resistance of the L is. . Worst

Another thing that the horizontal of an inverted L does for you on 160 is to give you a penalty-free loading device, so that the ENTIRE extent of the vertical wire can be seriously used for radiation

The horizontal section also radiates, more or less than the vertical depends on the specifics. Easy to see in a very simple NEC model. If you are opposed to radiation from the horizontal on principle
