I have read a number of threads on this antenna and I own one. It is about 38-40' in the air measured from the ground tot he bottom of the antenna. I have found 3 different guides on this antenna with different measurements but basically used the 4 inch and 8 inch rule on it. SWR are at 1.3:1 but I cannot seem to get any good reception or xmit. I was thinking about adding either a counterpoise or radials but wanted to hear if anyone has had luck with those ideas and if so what coax did you use and how did you install the counterpoise and or radials? I have some thoughts and will try when the weather gets better.
