Does anyone know where I can get instructions (preferably cookbook, but if they come with formulas, I can deal with that, too) for building a 2m SSB horizontal loop? I live in an apartment, which is pretty much a Faraday cage, but I get out pretty well from my balcony, at least to the east(ish) of the building. I have a discone out there right now, clamped to the floor stand of an old oscillating fan that it used to be attached to. :-) I have a similar portion of a floor lamp that I want to mount the loop onto. I need something that will cover at least the 180º that my discone can radiate in, as well as it does. Since 2m SSB is typically horizontal, the discone doesn't do too well. Any help will be greatly appreciated. There is an antenna that Cushcraft used to make called a big wheel. It had three full wave loops attached in parallel at the center. I have 4 stacked big wheels which suppress vertical emission and emphasize horizontal transmission. I have used this on 2M sideband and FM. If you can get the instructions for a single big wheel from an old ARRL antenna book, then I can give you some hints on phasing. I expect that you will only be able to stack 2 on your balcony. 73, Ed, N5EI |
