I wonder if anyone's ever used a kite in a field to keep a wire "up". I see kites a lot in the summer, along belt parkway here in Brooklyn and they seem to stay in one place for long periods of time. I'm sure one can use 12 or 14 AWG wire and let a kite carry it pretty high. Of course you need wind for that but being near water (salt water, no less) there's usually wind present. Hmm.....
The original German "Notsender," forerunner of the WW2 Gibson Girl emergency beacon [AN/CRT-5] used a folded box kite, launched by a rocket from an inflatable raft ... let's see -- rocket in an inflatable raft, this conjures up many scenarios, most of them bad. The CRT-5 operated on the Holy Frequency [600 meters] and had a weighted copper braid to drop overboard into the salt water, and the ones we had used balloons inflated with hydrogen to lift the antenna. That was problematical in anything but a dead calm. I doubt most kites in most situations would handle #12 or even #14 wire, the high part of the wire ends up being a long way up toward the kite.
Another idea that may be used to place a wire with a lot of precision is one of those RC quadricopters that are becoming wildly popular. A little servo "claw" to release the wire or just to place it's apex where you want it
Monofilament line, sounds like a great idea! Pull a Dacron line up and then the wire.
