I was wondering how much work has been done and would like to see some discussion on Loop antennas for 75 meter and 160 meter band. I for one have the most trouble with these two bands due things common for most hams. No tall well spaced trees on my property. No huge type antennas, or a way to put up long , very high wires. No huge towers to support any of these either. I would like to reference two web locations that discuss two type of loop antennas that seem to work very well. I plan on making a ground mounted loop antenna for use just for 160 meters and 75 meters made out of 2" aluminum conduit with joints being welded together and a correct size vacuum variable capacitor. see listed links.
? (3" aluminum tubing 15' transmitting magnetic loop)
(80 meter 2" aluminum loop antenna)

Nice read with plenty of info, been reading up on mag loops for quite a while now and never come across that site, thanks for posting the link very interesting indeed, would love to have a loop of that size but think it would create some serious problems with the local anti radio/antenna brigade I have surrounding me so a loft mounted frame antenna loop for 40 and 80 will be the next project, 160 will just have to wait worst luck.
