During March of 2025 RSGB Cymru (Wales) have been running a 15m 21Mhz challenge contest for members and affiliated clubs in regions 6 and 7. Participants are encouraged to build a home-brew resonant antenna for the 21MHz / 15M band, and make as many QSO’s as possible during the challenge.
David initially built a long wire at the club but could not get the SWR down below 4 so decided to turn to a delta loop antenna instead.
Davids antenna is a simple delta loop mounted 20ft up on a simple pole with 4 to 1 balun at the bottom. It is 47ft long with a lighting arrester attached to the bottom of the balun so that an earthing wire can be run directly to a 1 metre copper earth rod directly below the antenna. David has been operating the loop using his Icom 7300 and has made contacts all over Europe and Russia including several Italian special callsign stations that are currently partaking in the Italian Navy Coastal Radio Stations Award contest.
