Hi, All.
Brand new to the newsgroup, here, and even though I did the old "Find" routine, I couldn't find what I need. 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. -- -- 73 DE Tom Rutherford, N8EUJ, Burton, MI "She said it was either her or the ham radio. Over." |

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 |

Consider the fact that as it is on a balcony, I assume there is a building
with a balcony on the side, then you would do with a simple dipole as any signal sent into the building is only wasted. I am not sure but it would probably have a good off balcony signal pattern too -- better than most other antenna arrangements I can think of/ It's cheap and quick and wouldn't take much effort to try.

Irv VE6BP Quite. There's not much point in striving to achieve omnidirectional coverage if half the RF will be coming back into the building, and getting lost. However, in the interests of minimising interference (to and from the electrical devices in the building), it might be advantageous to minimise radiation/reception in that direction by using something at least 'somewhat' directional - maybe a 2-element yagi, or an HB9CV? http://www.mydarc.de/dk7zb/HB9CV/Details-HB9CV.htm http://webcache.googleusercontent.co...wa5UtoJ:www.wr aith.sf.ca.us/electronics/radio/+hb9cv+antenna+144&cd=8&hl=en&ct=clnk&sou rce=www.google.com and hundreds more. I might just go that direction, Irv, depending on how things look with other designs. Thanks! -- Ian |

I would go with a 2M QUAD, Very easy to build cookbook style. on site from scrounged materials. Ive used one from an apartment shooting through a balcony door. PVC mast was made from a couple of scrap pieces I got from the handy man. Pipe was selected so that one would slide inside the other. Apply padding to ends to protect ceiling and floor Think I wedged a piece of cardboard to lock the slip joint. Inovate as required. The quad can be asily put together with out benifit of test equipment and expected to function reasonably well without additinal tweaking. However a knockdown Yagi can be buit ahed of time and the elements stored inside the boom. Both are very handy. Jimmie |

I was wondering about the quad, what kind of a pattern it put out, etc. Gotta hit Google for some research. -- -- 73 DE Tom Rutherford, N8EUJ, Burton, MI "She said it was either her or the ham radio.
