Lee,
Just curious, what do you feed it with and where (corner or side)? Also, what are the shapes? I'm amazed at the flat SWR! 73, Al "DXer" wrote in message ... I have a 40 meter loop inside my 80 meter loop and have been running it for 3 years without any problems. Both antennas are flat (no SWR) and there appears to be little to no interaction between the antennas. 73, Lee - K1NT wrote in message ... Hi group, just wondering.... can I take a 40M delta loop and add an 80M dipole to it? Will there be interaction? SWR problems? Mark W4UDX |

The apex of the triangle is at 50 ft on a telescoping mast and I feet the
bottom right corner for vertical polarization. 40m is flat across the entire band .. 80m is flat from 3.500 to about 3.700 .... The base is about 5 ft off the ground ... /lee - k1nt "Al - VA3KAI" wrote in message ... Lee, Just curious, what do you feed it with and where (corner or side)? Also, what are the shapes?

What does one use to provide impendence transformation(if needed) at
feedpoint for a dual or multiband loop antenna? I have two...one cut for 20 meters that I wish to multiband and use individual loops for each band from 20 thru 10 meters. Could I use a 2 to 1 balun at feedpoint to resolve the impendence match? The second delta loop is top feed currently with twin lead...and had about 220 feet of wire in the loop. I would like to string in two more additonal loops...one for 40 and one for 30 meters.... Currently both are fed with 450 ohm twin lead with a pair of old Johnson Matchboxes.
