 ```Hello Bill, I have a 108 ft tower and have a 160 mts delta loop from top of the tower. You can do a delta loop where the sides are shorter than the bottom, as described in ON4UN book 4th edition page 10.6 "compressed delta loop" used by Bill W4ZV. But really I not found to have it 100%. I have a sloper pointing to north (0 degrees) and the delta lop is pointing to Europe (45 degrees) but I hear to Europe better with the sloper than the delta loop, and really this is not what I expect for the delta loop. 73, Jorge CX6VM/CW5W -----Mensaje original----- De: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] En nombre de Bill Parry Enviado el: Miércoles, 03 de Febrero de 2010 07:26 p.m. Para: 'Tower and HF antenna construction topics.' Asunto: Re: [TowerTalk] Feeding a Delta Loop Cort, I am interested in your antenna. I have a 120 foot tower and an inverted vee for 160 at about 100 feet in the center. I wonder if that delta loop would give me better performance? Every time I do the math, (160 M X 3 feet /meter = 480 feet/3 gives me 160 feet on a side and it doesn't seem to fit. How did you get it to fit. Do you have some kind of a coil to shorten it up in the legs?

Subject: Re: [TowerTalk] Feeding a Delta Loop Stu I tried just to reply to you but everything I tried ended up here.... but here is my experience... I have a full wave delta loop for 160 hung off at the 90 ft level of one of my towers.. sort of a tri-angle with the long side at the bottom about 8 ft off the ground. The whole antenna is tilted about 20 degrees from vertical and I feed it at the near low corner with a 4:1 balun... works like a killer and has great bandwidth. Bandwidth is about 100 kHz for 2 to 1 points and works great for transmit DX but not the best receive antenna in the world. My 2 cents...
