Antenna Switches, Diplexers and Triplexers for Sale in Melbourne, Victoria
Looking for a reliable antenna switch, antenna diplexer or triplexer for your amateur radio station? ComTek Radio has you covered with a premium range of signal management gear, available Australia-wide with fast shipping.
An antenna switch lets you connect multiple antennas to a single transceiver and change between them instantly — no more swapping coax by hand. Our antenna diplexer range makes it easy to run two bands through one feedline, with models covering HF, 6M, 2M and 70CM. Need even more flexibility? A triplexer splits or combines three bands (including HF/6M/2M/70CM/23CM configurations), so one antenna system can serve multiple radios or bands at once — perfect for contesting, field day operations and compact shack setups.
