I don't think that anyone is ... although I think the four element SteppIR has to be about the best single antenna 20-6 meter solution available. I'd like to try something similar to the 80 meter di

Has anyone built an inverted LPDA? Not practical unless you have the land and towers to support it but looks cheap to build and rugged. If you had the height it looks practical for 7-30 mhz. http://p

Construction details for an 80-40m wire LPDA are in the ARRL Antenna Handbook, 20th Edition. It could easily be extended to higher bands. You need a large family to rotate it and a large field if you

I've always thought that since the beamwidth is fairly wide (90 degrees-ish) that you could build 4 or more around a central point, and then use some sort of power dividing scheme to "rotate" the bea

Seems like a good idea, except the parasitic elements of the other antennas really mess up the pattern, etc! I took a standard LPDA and put one 10' away firing into the original and removed its sourc
