Hi Stan, I've built a number of mag loops. I've used aluminum tubing, copper, and hard-line coax as the main sections. I purchased a dead AEA HI-Q loop unit on ebay for cheap years ago and pulled the capacitor off it.
The ERP is off-course compromised compared to a dipole. However, its advantages are: - small size - super quite - Vertical or Horizontal polarization - In vertical polarization it is broad-side directable. Using 2-3" copper fully soldered together as the main body will increase your ERP. MFJ has a box loop which uses a wire. But a ham can pull their wire off and replace with copper pipe. In the right size diameter, one and work both 40 & 30 meters no problem. Have fun with your design!!!! :) Duane N1BBR -- [email protected] ______________________________________________________________ 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
