TELEWAVE's crossband couplers allow transmitters, receivers, and antennas in the 132 – 174 MHz and 406 – 470 MHz bands to share a common feedline. A single coupler can be used to couple two radios to a multiband antenna, or a multiband radio to two antennas. Two couplers are used with two radios and two antennas. The ability to share a feedline between systems on different bands simplifies installation, while reducing cost and tower loading. No tuning is required for full band coverage, and each unit is completely weathersealed for zero maintenance and long service. The TS-1545H combines 132 – 174 and 404 – 470 MHz signals and can handle 400 W per input.
