And I'd like to emphasise that this thread is about physically small "magnetic loops", not fullsize quad or delta type loops which are efficient radiators with relatively high radiation resistance, in my experience. I have used fullwave wire loops on 80, 40 and 30m for both TX and RX with great success. By the way, I don't know if it's the same with magnetic loops but the fullwave loops radiate mostly "broadside" to the plane of the loop. If the loop is vertically oriented (e.g hanging between two trees), the polarization of the signal is determined by whether the loop is fed at a horizontal or vertical section of wire. If the entire loop is laid 'flat on its back', most of the radiation heats the ground, some heats the clouds but I'm uncertain what polarization the signal would be - probably horizontal I guess since all the wire is parallel to the ground but I may be wrong. 73 Gary ZL2iFB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
