I am moving from my current QTH where I have a horizontal loop up about 35-40 ft. that is a bit longer than 1 wavelength on 80. I feed it at one corner with 450 ohm twin lead connected to a 4:1 voltage balun, then coax to my rig. I can tune all the ham bands either barefoot to my K2 or KX3 and the KXPA100 using their internal tuners.
My new QTH will not have the real estate to do what I can now. I was hoping someone who is well versed with the EZNec antenna program could give me an idea of how well what I think I can build, will work. I will have a yagi for 10-15-20. I am particularly concerned that I may not be able to tune 80. I have a Sunday CW qso with a group of great guys on 80 and want to keep participating. Here is the info on the new horizontal loop: The east side will be 54 ft. long and be 2 ft. above my roof at a 35 ft. height. That leg of the loop will be over a roof that slopes away for about 8 feet. The west side will be 78 ft. long and up 20 ft. The remaining north and south sides will be 38-40 feet each of the same length. This will give a loop a bit longer than 200 ft. I plan to feed it again on a corner, the NE corner when it is two feet from the roof and I can run the twin lead down the side of the house to my shack. I know this will be predominantly a cloud burner, but that is fine on 40 and 80. My concern is being able to tune it on the 80, 40, 30, 17, and 24 meter ham bands. My lot is only 80 by 100 so a doublet on 80 will not work without folding it in several locations. I have loved my loop and would love to be able to continue using one. The fact that it is horizontally polarized is so nice for being able to work weak stations without a lot of noise. If anyone could help me with the analysis of this antenna, I would appreciate it. 73's, Terry, N7TB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
