Horizontal corner dipole; length 2x 7m, height: 5m AGL. Connection: 16:1 transformer + 13m H155 into shack.Over some 15 years there have been 11 versions of the ' ideal 14-28MHz antenna'. Varying from single wire-verticals/rigid alu verticals to several better performing multi-vertical-wire GP's. But during the last 5 years local man-made nose became a more dominant factor and I had to start experimenting again.A very low NVIS like corner dipole, used for high-angleRX on 80/160 was raised from 1m80 to 5m AGL to make it work as a DX antenna on 14-28 too. Via a triplexerfilter it is now fed into several RX systems, one of it being this FAROS IARU/NCDXF HF Beacon Monitoring system.
