For anyone interested in building their own HF antennas this should be of interest. On the top row are parts from a Hy Gain TH3 Mk3 antenna. Then you'll see the two plastic end caps to fit the 2 diameter boom.
Then the driven element to boom assembly with the two inserts that isolate the driven element from the boom. Next the reflector and director element to boom brackets. Clean up the pieces, treat yourself to some new nuts and bolts then design a three element beam optimized for the band you want and you're all set to go. Oh, don't forget you'll need some aluminum tubing for the boom and elements.
But wait, there's more! On the second row there's a centre piece that originated on a Cushcraft D3W rotary dipole for 12/17/30m.
Fit this to your mast and use it for a rotary dipole. Then there is a mount for a vertical antenna with a SO-239 connector for the feedline. Next is a RAK dipole centre with built in balun for your wire dipole with two substantial end insulators. Finally a 1/4 Inch thick aluminum plate 8" by 4" that can be fixed to your mast to support another antenna. This piece needs a second saddle mount but doubtless your local muffler shop can help out.
