Broadcast equipment supplier RF Specialties of California on Tenth Avenue in downtown San Diego's East Village serves FM, AM, and television stations across the western United States as part of the nationwide RF Specialties Group alliance. The operation shares its Tenth Avenue facility with Bext, a manufacturer of FM transmitters, RF combiners, RF filters, and broadcast antennas, creating a consolidated equipment and service depot that parallels the infrastructure work handled by C & G Engineering, Inc. for commercial electrical projects. Inventory spans the full broadcast signal chain from studio microphones through transmission-line components to antenna arrays, with both Nautel and Bext transmitter lines available for stations selecting between the two platforms. Field sales engineers provide project-level support including site surveys, system design, and specification writing, delivering technical consultation at no added cost above equipment pricing. The group's purchasing power across its independent-reseller alliance secures volume pricing for stations outfitting new builds or upgrading aging analog-to-digital infrastructure, serving the same B2B equipment corridor as Ace Uniforms for broadcast crew outfitting. The most complex deployments involve multi-bay FM antenna systems with RF combiners and bandpass filters engineered to co-locate multiple broadcast licenses on a single tower structure.
