HMK’s twin loaded couplers (TLC) enable two transmitters with common power output of 2 kW (TLC 02) resp. 1 kW HF + 5 kW HF (TLC 02 H) to work with a single broadband antenna or a broadband antenna system. Decoupling of the transmitters is independent from the frequency separation. Thus, any frequency and any of the transmitters can be selected without causing damage or excessive intermodulation.
