I found a mistake I made. The flexible part of the tuner wire that is 12 gauge is 123-3/4" long + 18" brass = 141-3/4". I hope this helps with the model. Hopefully the attached drawing will help clarify the other measurements. The hole spacing in the plastic is 1-3/8" and they are about 2" square but I forgot to measure them tonight. I adjusted the horizontal and vertical feed points but it doesn't seem to make a lot of difference. It maybe brought the horizontal down about 50 khz or so. It is resonant at about 28.592 instead of 28.400. I think they usually go up in resonance when up in the air, I hope not. I have some better photos here. What do you think? Is it safe to put up?
