Have you ever tried a standard vertical antenna? Just usual rain fall tube and cheep loudspeaker cable and a 10m vertical on the top of the house will give you up to 20 dB signal improvement at the same power levels i guess. I also decided to do my first transmissions with the new coil at 1W TX power, just to see what is possible :-) 73, GL, Stefan/DK7FC
