The 510-13 (CH20-13) has been computer designed to cover the entire channel 20 bandwidth plus extra bandwidth on the high side to account for weather effects. The clean pattern provides more reliable signals with less interference. An optional stacking harness is available when more than one antenna is required for reduced beamwidth or additional gain. Users are surprised by the performance of this compact but potent antenna.
Construction is classic M2 for long term electrical and mechanical integrity. Elements are 3/16" 6061-T6 rod, mounted through the boom on UV stabilized insulators and locked in place with stainless steel shaft retainers. The driven element module is CNC machined and all connectors are O-ring sealed. Internal connections are encapsulated in a space-age silicone gel with nearly 4 times the dielectric strength of air. Balun connectors are triple-sealed to the coax. Single channel models can be manufactured for all television and FM applications.
