  Crossband Coupler

Sinclair's new crossband couplers allow transmitters, receivers, and antennas in the 150, 220, 450, and 800 MHz bands to share a common feedline. Two couplers are required for each installation. 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 weatherproofed for zero maintenance and long service.
