Opek CX-5 3-Way Coax Antenna Switch SO-239, DC–500 MHz, 1kW

The Opek CX-5 is a heavy-duty 3-way rotary coaxial antenna switch with SO-239 (UHF) connectors, covering DC to 500 MHz — ideal for amateur radio operators who want to switch between multiple antennas from a single transceiver without disconnecting cables. Rated to 1kW PEP up to 200 MHz and 500W PEP from 300–500 MHz, it handles everything from HF through VHF and into UHF with ease.

The rotary selector gives positive, tactile switching between three antenna ports, with 50dB isolation keeping signals clean and separate between positions.
