Hello Jean-François, I think you will be very pleased with the MP-1. I used mine with a K2 from inside a 6th floor hotel room in Tourcoing, France during the WPX contest last May and made several contacts of 1500-3000 km on 20m at 5W through the heavy EU QRM.
Even a 1/8-wavelength counterpoise as you described is adequate to get the input impedance to a point where the antenna tuner can easily match the antenna. I use the 4SQRP Tenna-Dipper to easily tune it to my operating frequency. I found it helpful to have a 3/8-24 tap, as the threads tend to gall fairly easily if you assemble/disassemble it often. 73, Bob N7XY ---- Bob Nielsen, N7XY n7xy (at) n7xy.net Bainbridge Island, WA http://www.n7xy.net _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
