I set up a simple end fed antenna with a counterpoise. The end was held up on a 6m squid pole tied to a steel garden stake. I had a contact on 40m. Peter, VK2EMU, hung a giant dipole out to two trees and operated on 80m.
The most interesting station was Colin, VK2JCC, who put up a magnificent squid pole supported vertical. The rig was a wonderful military radio called a Clansman PRC320 that seemed to work very well.
