After combining the RF power lines with the cascaded 3 dB coupling devices, the RF transmit signals are routed to an HF broadband antenna system, which may consist of an R&S®FK2950 antenna triplexer and a three-section broadband antenna.
A two-section antenna (e.g. twin fan) and diplexer/matching unit may be used for smaller systems or ships.
An antenna mismatch of up to VSWR 3:1 can be tolerated without loss of power. For land-based installations single broadband antennas (e.g. log periodic antennas) from 1.5 MHz to 30 MHz can be used.
