Product Description
The dmb20-20 is a dual marker beacon coupler that combines one 75 MHz marker beacon antenna signal to two separate navigation receivers. This RF splitter uses 50-ohm BNC connectors and provides high isolation between receiver ports, preventing signal degradation and cross-talk. Compliant with FAA TSO-C53d standards, the coupler enables ILS marker-beacon system installations where a single airframe antenna must serve dual receivers.
Installation follows standard 50-ohm coaxial practices and avionics installation manual specifications. Critical for maintaining independent receiver operation in redundant navigation architectures.
