The Diamond CX210A double antenna switch is a commercial-grade, low-loss coaxial routing instrument precision-engineered to toggle a single transceiver between two antenna systems, or conversely, link two radio terminals to a single radiating array. Manufactured by industry leader Diamond Antenna, this heavy-duty mechanical selector operates continuously across an ultra-wide spectrum spanning from DC up to 1000 MHz (1 GHz). It serves as an essential logistics procurement component for complex base station builds, emergency communications dispatch command centers, radio frequency calibration bays, and high-volume B2B radiocommunication hardware wholesale distribution channels looking to secure market-leading RF distribution stock.
The high-integrity internal cavity design of the CX210A delivers exceptional isolation metrics and minimum insertion loss tracking, protecting sensitive receiver front-ends from adjacent channel crosstalk. Engineered to manage high-power transmission loads without contact arcing or thermal failure, the internal matrix safely handles a maximum input power capacity of 1500 Watts (1.5 kW) PEP. Outfitted with three heavy-gauge, gold-plated SO-239 (UHF Female / PL) socket interfaces, the switch ensures a solid, low-VSWR connection path when coupled with standard PL-259 terminated transmission feedlines, maintaining a stable 50-ohm system architecture.
Housed in a compact, ruggedized die-cast metal enclosure measuring exactly 71 x 57 x 42 mm, the structural chassis shields internal contacts from external electromagnetic interference (EMI) and harsh physical workbench or mobile vibrations. The high-retention rotary selector lever provides an immediate, positive tactile feedback lock during terminal swap maneuvers, preventing accidental half-position switching. Delivered completely turnkey, this premium 2-way coaxial switch ensures immediate technical system alignment, effortless rack or bulkhead mounting, and absolute multi-shift field deployment readiness.
