Been trying to get up to speed on these...Learned that height is not important, as it's the tower that will radiate, primarily. My tower is 70' with a Steppir 3 ele and other assorted antennas for VH
Greetings Ed -- Please forgive me, as I did not mount my example of that antenna on a tower, as you plan to do. Nevertheless, my experience might be helpful as you decide whether or not to try that a
Ed: I will share my experience with a 1/4w 80m sloper hanging from my tower with 3el SteppIR on top. The sloper is homemade, about 72 ft long, hanging from the tower at about the 72 ft level, and mak
Ed - I had one of those. I never got it to work even moderately well. As I recall, it was mounted at 35 feet, which is what I remember the instructions called for. That said, my rememberer isn't too

I have a similar halfsloper (40/80/160) attached to a 55-foot crankup tower with a SteppIR on top, I initially attached the sloper to the top of the tower, but later moved it to the top of the middle
I really don't think it's the tower that radiates. I use a relatively steep 1/4 sloper on 160. It tuned just like any other antenna with pruning and seems to favor (slightly) the direction in which t

I have the 160-80-40 twin sloper attached at 50' on a rohn 25 tower a couple of feet below a force 12 c3 triband beam. I have 3 buried 35' radials connected to the tower legs and have no room for mor
Dear Bob: I, too consulted ON4UN's book, as there are few other sources that explain this well. A couple of questions: 1) How tall is your tower and is it a crank up? 2) How did you go about coupling
