Raymarine 4kW Digital Pedestal Magnetron (Service Part)

This is a genuine Raymarine replacement magnetron for the 4kW Digital open-array radar pedestal. The magnetron is the microwave valve that produces the radar transmit pulse, and it is a consumable wear item: because the heater runs in both standby and transmit, the valve's output falls gradually over a long service life until it needs replacing to restore full range and target detection.

Fitting a new magnetron refurbishes an otherwise sound 4kW Digital pedestal rather than replacing the whole scanner. The work involves high-voltage circuitry and the waveguide, so replacement and re-tuning must be carried out by a Raymarine dealer or a suitably qualified marine electronics engineer. This is a genuine Raymarine service part supplied for the repair of an existing 4kW Digital radar pedestal.
