The 122-4BBA antenna uses a driven element module originally designed for maritime ATS satellite service. All connectors are O-ring sealed to a CNC machined aluminum block. Internal connections are sealed in a silicone gel with nearly 4 times the dielectric strength of air. The balun connectors are triple sealed on the coax and nut-sealed at the block connectors. The type “N” feed connector uses a gold-plated, beryllium copper center pin. Other key electrical and mechanical components are CNC machined for accuracy and durability.
Elements are 6061-T6 3/16” solid rod, centered through the boom on UV stabilized, polyethylene insulators, and secured with stainless steel shaft retainers. Thousands of these type elements are in commercial service with NO failures. The boom is constructed of 6063-T832 aluminum alloy tubing. All hardware is stainless steel except theU-bolts. For uncompromising performance and long term electro-mechanical integrity, the 122-4BBAis unmatched.
