Well, Carl Your thoughts on radials are pretty much like mine! For those of us with limited space, another way to get the 130' elevated radials into limited space is to bend them. I've had really good success on 160 by doing that under and inverted L (about 70-80 feet vertical) I try to arrange to get the first bend out 60-70' from the base of the inverted L. Works pretty well!
What helped me the most on 160 and 80 was when I built KAZ style terminated loop with a preamp for a receiving antenna! Suddenly I could HEAR stations on 160 that I didn't even know were there! It also worked very well as a receive antenna on 80, 40 and 30m! Sure helped a lot on my modest city lot!! (With too many tall trees!)

I use whatever I can find at the lowest cost which has been mostly #16 and 18 stranded and insulated in 500-1000' reels at a local surplus shop. Ive even used #22 when the other wasnt on hand and it was a weekend. With the current split thru a sufficient number of wires there shouldnt be any unecessary loss. You can also run a thicker wire for the first 50' of so where the current is highest and then splice in the smaller wire. This may be of interest when having to buy new wire at retail cost. There has been very little breakage here from storm damage over the decades since the wires just lay on the branches and are not tied off tight. The sine wave droop is a good way to get 130' of wire in less horizontal space (-; Carl KM1H ----- Original Message ----- From: "Rick Kiessig" <[email protected]> To: <[email protected]> Sent: Friday, December 14, 2012 9:29 AM Subject: Topband: Optimal radial wire type and gauge? > The recent talk about optimizing the number of radials has me wondering > about the optimal type and gauge for radial wire.
