The SW-3 is a high-power 3-way coaxial antenna switch with N-type sockets, covering DC to 1500MHz and rated for up to 1.5kW on HF — suitable for amateur radio, HF, VHF, UHF, and mi crowave installations where high power handling and very low insertion loss are required. Four N-type sockets in total: one common port and three switched ports. The SW-3 offers lower insertion loss than the SW-4 across the full frequency range, making it the preferred choice where signal integrity is the priority. For a 4-way version, see the SW-4.
