I have had some surprising results with a 40M mag loop I built from hardline (real cheap) as well as an *all out* (that means big bucks blown) 20 meter mag loop that I built from 1.5" copper pipe, a Jennings vacuum variable, and a 1 rpm motor from Edmunds Scientific. My best DX so far (confirmed) is UA1CE on 900 mw on 20M with my KX1 for about 6500 miles. The darn thing was sitting on my driveway about 3" off the ground.
My personal findings: Superb receive antenna; lousy transmitting antenna; highly directional; Incredibly quiet compared to my doublet; extremely narrow bandwidth. It's presently sitting in the garage. I haven't given up on it but I much prefer my doublet and end fed half wave toys at this time. But frankly, for someone - anyone - who has *severe* antenna restrictions to contend with, the mag loop is most certainly worth reading up on. It's not a toy! 73, Stan WB2LQF On Wed, Jan 4, 2012 at 5:52 PM, Gary D Krause wrote: > Ignacy, I agree. That's why I like mag loops. I've built three of > them and I'm getting ready to build a forth.
