On Friday 20th July the annual portable event antenna event took place. Members must erect an antenna within 30 minutes on the club site for the selected band (30m this year) and then a series of transmissions are made using a low power TX with each antenna.
The Reverse Beacon Network is used to analyse the results of the transmissions to establish the performance of each antenna. Two sets of transmissions were made within a 30 minute period.
Congratulations to Clive G4NAQ with his 1/4 vertical using a Mad Dog coil out performed all the other antennas (just about).
Some commentary from Paul G0OER who ran the event.
- A shame one entrant turned up without his antenna ! (event 2 on 9th August)
- all antennas were resonant on the 30m band (after some help with an analyser for one late arriving entry)
