The Avair AV-SW2M is a commercial-grade, high-isolation 2-port coaxial antenna switch engineered to manage RF distribution infrastructure between multiple transceivers or antenna arrays. Capable of routing signals seamlessly from DC up to a high-frequency threshold of 1000 MHz (1.0 GHz), this heavy-duty mechanical selector utilizes a precision-machined internal cavity layout to maintain absolute impedance continuity. It stands as an essential physical utility asset for centralized base stations, communication service facility benches, marine radio installations, emergency response command nodes, and high-rotation B2B electronics wholesale distribution networks.
Built to sustain intensive daily rotation and execute reliable RF path cross-overs under extreme power loads, the heavy-duty metallic enclosure delivers exceptional isolation metrics—reaching over 70 dB below 500 MHz—to prevent mutual cross-talk and protect sensitive receiver front-ends from adjacent high-power transmissions. The coaxial interface layout features three low-attenuation, precision-threaded PL Female (SO-239) bulkheads (one primary common input and two dedicated channel outputs) calibrated for a stable 50-Ohm system profile. With an impressive peak power handling threshold of up to 2.0 kW in the HF band and a negligible insertion loss layout, this premium antenna switch allows system integrators to streamline equipment racks without experiencing signal degradation or impedance mismatches.
