John Moyle field day which encourages portable operation from portable power. Peter, VK2EMU, kindly invited me to join the team from the St George Amateur Radio Society who had arranged a wonderful location at Oakdale, west of Sydney.
The gang had a veritable antenna farm with everything from 160m up to UHF. I was planning to just use the 20m vertical on the van but Con, VK2FCDL had a new off centre fed dipole that he was keen to try out of China. It's called a BG7PNV HF20A Dipole and it tuned up beautifully on both 20m and 40m. It claims to work with low SWR from 500KHz up to 30MHz and while I can't vouch for that, we had contacts on 20 and 40m. There is a big resistor in line very near the end of the long leg, perhaps that keeps the SWR low?
It was a warm day but with a very pleasant breeze.
