Here's his e mail to me on his setup. Think it should read one leg N/S and the other is E/W. Note that it is at 20 feet! Appears to work. Jay W1VD WD2XNS WE2XGR/2 ____________ Jay, I have an ICOM 706MKIIG feeding aqn attenuator which feeds a transverter from 7.2 MHz to 500 KHz. The transverter is feeding a solid state amp. I am running about 10 - 15 watts ERP. The antenna is a half wave dipole on 500 KHz about 20 feet above the ground in a N/S and E/W configuration. one leg is N/S and the other is N/S. I am listening on a ICOM 756PROII and a HyGain Hytower. 73 Jim WD2XSH/35 K0HW ----- Original Message ----- From: mal hamilton To: rsgb Sent: Thursday, January 14, 2010 10:45 AM Subject: LF: 1/2 wave 500 Hi Has anyone in the USA tried a 1/2 wave dipole on 500 K/cs? inv V design, at a modest height around 100 ft. de mal/g3kev
