I am contemplating the construction of a dual band inverted L for 160 and 80 meters. It would be a quarter wave design with a sloping top and mounted off of the side of my self supporting tower. I ha
I am thinking of that same sort of thing - have pretty much the same constraints as that guy. My friend has one, and is not happy with it, but I fear his is detuned by so many other stuff hanging off
Pat, what are the details of your trap? I'm using an inverted L for 80m, about 5' away from my tower and have been VERY happy with its performance. I've often thought of putting a trap in it and exte
Greetings Hasan, Check out OK1RR's excellent site, http://ok1rr.com/e107_plugins/content/content.php?content.38 specifically for an antenna called the Battle Creedk Special. It is a well-known antenn
why bother with a trap--it will only quit working eventually. Why not simply run two wires spaced apart, one about 1/4 w. on 160 and the other half that length for 80, an inverted L version of the fa
how about a remotely controlled switch/relay you could used to switch in extra wire, or not, as might be your whim, switching from the shack? That would let you have both lengths of wire without addi
Hi Pat I'm using a KW-80 coil from Unidilla here. It works really well. I have my anenna set up as an inverted L and am very pleased with it. I have it set for the CW band and the SWR is low on both
What 80 meter vertical did you install? A wire or home brew antenna, or a commercially mfd antenna? == -- _______________________________________________ _____________________________________________
Thanks to all those who have replied to my plea for help on a lowband system for 160/80 on a single tower. I've done some more modeling with MMANA this evening to give me an idea of the pros and cons
Geeze, Pat... those plots all show a rather narrow bandwidth on all the options. What does the modeling program say about the old fashioned V dipole? How about a sloper like the Alpha Delta DX-B sing
W9INN had a good design that used a trap and was only 115 feet long (full size on 80). I had it up and for a short time before a storm took it down. With just a ground rod and two radials I did very
