I'm looking for a 5 band yagi (10,12,15,17 &20 meters) that has more gain than the 2 element per band designs. I prefer no traps. Steppir is not an option as I will use the antenna on two bands for

Hi Rich, Why do you need WARC bands on antenna which is going to be used by SO2R via a triplexer? That implies contests... no need for WARCs. Get 2 beams, 10-15-20 [a lot of choices] and 12-17 [I am
Rich, I was looking at the Hy-Gain TH-11 but I do not like traps. I have considered the EAntenna 59+ (http://www.eantenna.es/)log periodic. It seems to fill the bill for coverage, footprint, and numb

Align by sight? Ever hear of a level? When I first got back on the air, I used a TH7 for about 2 years. When I put that antenna back together (I had it stored in my garage), I bolted the boom
Exactly. Milled aluminum that are bolted to the element plates. The elements are installed using polyamide clamps on the bottom of the element plates. Look up polyamide. Kevlar is a polyamide. The bo
