[UK-CONTEST] Antenna for SSB field day

[Andy Summers]

  Good luck to anyone who manages to get a 5-band log-periodic into the 
air - and turn it! But seriously, I think even the most obtuse would 
realise that isn't a 'single element' antenna. It's in the vernacular to 
talk about, say, a 10-ele log-periodic.

Regarding the supports, have you noticed that the rules only say the 
antenna must be 15m max, not the supports?

Thanks to Ed, by the way, for the clarification. Sorry to have stirred 
things up a bit outside the official channels I was pursuing, but I 
couldn't help but reply to the very same questions I'd been asking.

This is what we used last year, for the curious...

Sadly, it's looking unlikely we'll be on in SSBFD this year, at least 
not with a serious effort.

73,
Andy, G4KNO.
