I started a fad with a bunch of newbies by suspending a twin lead j-pole up in a tree.
Some of 'em bought SWR meters, antenna analyzers (for those who had the money), soldering irons, twin lead, coax, and the PL-259 plugs. A lot was learned, but we had a few frustrated dropouts who had their buddies build them. We built dipoles and "coat hanger" verticals too. I politely refused to build any, and deflected by insisting on the learning experience.
Later, I stuffed that twin lead J-pole in a PVC pipe for mast mounting.
