Finished up my new Field Day antenna well ahead of the actual date for once. It's a wire Moxon beam for 15m and the whole thing can be carried and erected by one person. I wouldn't want to lug it up a mountain or anything but since most of the weight is in the surplus fiberglass camouflage netting supports I'm using for masts, it would be easy to shed weight by using a pair of lighter poles.
Here's a picture of it collapsed for transport:
It stands about 20 feet tall when it's set up, and is about 17 feet long by 6 feet wide. That's about 6m x 5m x 2m for those of you in the more civilized countries.
