Hi Gary. The antenna has six elements on a 17 foot boom. Below are the approximate final dimensions as I may have changed things slightly since then. The hairpin aka Beta match is simply a piece of stainless steel filler rod used in welding. The antenna had a former life as a Wilson Shooting Star 11m antenna and I was able to use the original element to boom clamps with muffler style U-bolt clamps.

Feedline and balun attachment point. Driven element is insulated from the boom with Plexiglass. The center of the element is fiberglass rod.

Half wave coaxial balun attached. Feedline connects to the middle SO-239 connector.

Old picture showing it at 42 feet on the old tower. Notice the wrecked A3 tribander below it with only one element left attached to the boom. Since this antenna was originally an 11m antenna and shortened to 6m it makes for a VERY heavy duty antenna.
