I have a 40M off-center fed dipole hung as an inverted vee about 25’ up in a tree in my backyard with the ends about 8-10’ off the ground attached to my fence. It works pretty well and I have made contacts with Canada, Puerto Rico, Italy, Croatia, and Serbia on 40M and 20M. How much better will it perform if I can get the center up to 35’ or 40’ (I.e 10’-15’ higher). At that height, the center will be above my roof. On a percentage basis 10’-15’ is quite a bit higher than where it is now. Curious to know if the effort will pay off or not.
