I am currently building out an inverted vee for 40/80. the height is about 38-40ft. I have a smaller lot so I am unable to have the elements full size, I am limited to at most 50ft. per leg. Currently I have a ~140ft. vee with about 25ft of each leg running parallel to the ground about 5ft in height, in a "Z" shape, fed with windowed 450 ohm line and the smaller johnson matchbox. While the antenna works, I am not happy with the current distribution on 40m. The plan is to put up a loaded vee. I have coils made up, about 60-70uH. I have built and varnished them so that variable is pretty much set. Modeling this antenna, the current nodes on 40 are higher along the elements than the 140 unloaded vee, which is what I was shooting for. My concern is ground losses. I have a couple of questions before I start cutting wire. Parameters: I have ~110ft of ladder line, I would like to leave the feedline length the same. The loading coils are constructed, 60-70uH. I do not want to rewind them. ~50ft per leg max element length. Running models, the numbers are close. if I cut for ~390 ohm feedline, the element ends are ~4ft above ground and the loading coils are about 10ft above ground. If I cut it a bit shorter, I think I can still match with the matchbox, and the ends would be 8ft above ground with the coils 13 ft high. My concern is ground loss. I want to make this antenna as efficient as possible. Am I splitting hairs at this point? Is the 4ft addition in height going to matter much as far as ground losses?
