I was thinking it was a lamp shade for the drunks to wear when the party gets really crazy. The antennae is so the host can communicate to the drunk that the party is over without having to yell, therefore angering nearby campers. That tripod is simply the rack for it. Once the lamp shade is on the tripod, the party is over.
