Here are some shots of one of the most interesting and inventive products at the flea market outside. This guy manufactures and sells a Carbon Fiber Portable Antenna Mast system that breaks down into a bag. That doesn't sound like a big deal until you see it in action.
It comes complete with the tripod, mast, a couple of stand-offs to mount antennas on top, guy rope, anchors, and
block and tackle system. To assemble this system, you put the tripod together, then insert a mast piece into the tripod and assemble the stand-offs and block and tackle. You then use the block & tackle crank to raise up the mast from the center of the tripod and add mast pieces from the bottom. It was so easy that you could raise a portable antenna up by yourself. This was probably one of the most well designed portable systems at the show, and the price was very competitive. Unfortunately this guy doesn't ship them anywhere, so you'll have to find him at hamfests:
Here the tripod has been assembled and the first section is being raised up:
Putting another section in from the bottom :
Everything fits into the bag:
Raised up about 30' with guys attached to water jugs:
