I have a K3 with the second receiver and I’d like to utilize it with a receive only antenna. I have a horrible intermittent noise that I cannot identify and is heard state-wide at the upper portion of 80 m. I’m hoping a small loop antenna might help null that noise or at least a lot of it.
I know I want a small loop. Well, maybe... I have looked at small shielded loops, small shielded mobius loops, mag loops, etc. I have a friend who came by and once recommended that I string up a random length loop around the top of my wooden privacy fence. Some of the privacy fence needs to be repaired and/or replaced. The height of the fence is about 6’ and I could come down 12 - 16” from the top of that and run screw-in ceramic insulators. Except for the portion that’s my house, the privacy fence runs the perimeter of my back yard. I could use this on 160 m if I don’t use a preamp or have the preamp switched out. Whichever route I take, I’ll probably use the small preamp from Kits and Parts at the input of the antenna. I have access to solid conductor LMR-400, I even have about 40’ of 7/8” hardline, but I want something that’s not real cumbersome. I think the mag loop may be easier to construct but none of the small loops look extremely difficult. I am, however, a tad confused on how to couple a shielded loop to the preamp. Can I just use alligator clips and run those to the shield and both conductors? I don’t see why I could not connect a preamp at the input to a mag loop. I could take the mag loop portable with me if I wanted. I’m just looking for some advice and if y’all think this is too far off topic, please respond directly. Thanks. 73, Joel - W4JBB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
