saw that a "verticals radiate poorly in all directions" is generally true. You need a superior ground, like salt water or a marsh. Two of my installations, including the HF2V did well (OK to well) on 40M with extensive grounding. 120 radials, one in a field and the other dug into a lawn. The soil on Long Island is sand or clay and rocks. Both are terrible grounds. If you can erect them as ground planes they will generally work better. The F12 vertical is interesting, because it is a vertical dipole and should not be too dependant on the ground. Sidenotes: Butternut is a well constructed, tapered, antenna and survived many storms, including ice storms. They recommended 45 degree top loading (about 2/3 up) to make it broad banded. I put 4 top load wires on the antenna and the performance SEEMED to go down. During a windy week, performance got a little better. It seemed that as each top load wire broke off the vertical component improved. My last ground plane was done with aluminum fence wire. Over the years I noticed that the vertical performance was decreasing. When the grounds were re-landscaped and dug up for sprinklers and lighting, the ground wires came up. I discovered that the aluminum wires had all but disintegrated in the ground. Jim > I've considered a Butternut HF6V or HF9V, but would like to hear about the > F12 verticals available.
