Air Coax Center Post, Equipped for 6 Bands
The Air Coaxial Center post is made of polished aluminum and stainless steel and has six sets of terminals for a hexbeam with up to six bands. The center post fits into the top of the base plate and has an eye bolt on the top for anchoring radial support cords that extend to the ends of the spreader arms. The insulators on the terminals are PTFE for high current and heat resistance. Your 50 ohm coaxial cable connects to a high quality Teflon insulated SO 239 female connector mounted at the top of the center post for an ideal match to the hexbeam. Moisture and UV radiation are not a problem with this premium quality center post.
