The De-icer must be incorporated in the factory. (not the field job)
The performance monitor (PM-51) is built in the Gearbox. The PM-51 can be mounted
in the field job. The antenna revolution speed depends on the type of the Gearbox.
Use a transformer unit when the specifications of Antenna motor power are different
from ship’s power supply.
The Antenna motor power is supplied to the Gearbox via the Power supply unit,
PSU-007. The PSU-007 is composed of Relays and Thermal switches.
A note should be taken that an Antenna radiator; SN-30AF (10 ft) of 21/26 rpm does not
adapt with the IMO radar in terms of the bearing discrimination. However, the HSC is
adapted.
