The KIO Hexbeam features a very strong center post made of 6061 T6 aircraft grade aluminum providing a good match for the driver elements of the hexbeam. Terminal insulators are made of teflon with a teflon insulated coax connector. With all stainless steel hardware, there is no wiring harness at all in this asymmetrical air coaxial distribution device. It fits snugly into the base plate and extends 8 inches on the bottom of the baseplate making it easy to affix to the customer supplied hex beam mast.
