AM Transmission Accessories
Complementary equipment for medium wave antenna systems
Antenna Tuning Unit (ATU)
Designed for the medium wave band (530–1705 kHz). Available in sealed-box or open-panel configuration. Broadens antenna passband for HD Radio and IBOC digital operation.
Intelligent Combiner
Microprocessor-controlled combiner for the medium wave band (530–1705 kHz). Nominal input power: 1–50 kW per port. Combined output: 2–100 kW.
Transmitter Switch
Automatically switches between two transmitters and a single antenna system. Models CMT-5/5 (5 kW), CMT-10/10 (10 kW) and CMT-25/25 (25 kW). Single-phase 220 V 50/60 Hz supply.
