I'd buy a bunch of that flat green fiberglass military mast. You can
drill & tap it where you want to bolt a loading coil to and use a wire
spiral wound up the mast to the coil then onto the tophat which is again
bolted to the top mast section. Use ropes to guy it and it will stay up
there until you want it down or a tornado takes it away...
Super easy, very low cost, low visibility, and big on the cool factor!!!
