I think the main (and maybe only reason) to use long and low horizontal wires on 136kHz is an attempt to produce a strong skywave signal for 'DX'. So it would be worth not only to compare the perforance of these antennas (versus the more classic short verticals) on a transmitter only 500 ... 800km away but also a 'real DX' in the 2000 ... 3000km range. Maybe the 'Greek' at the bottom of the band can be used for that ? 73, Rik Rik Strobbe ON7YD rik.strobbe@fys.kuleuven.ac.be Villadreef 14 B-3128 Baal BELGIUM (JO20IX)
