Performance has been computer optimized to meet your application. Physical construction emphasizes long term electrical and mechanical durability. Elements are 3/8” 6061-T6 aluminum tube, mounted through the boom on UV stabilized polyethylene button insulators, and locked in position with stainless steel shaft retainers. The driven element Folded Dipole uses a CNC machined central block with O-ring sealed connectors. Internal connections are encapsulated in a silicone gel with a dielectric strength 3.7 times greater than air for enhanced power handling. Balun connectors are triple O-ring sealed to the coax.
