The De-icer must be incorporated in the factory. (not the field job)
When mounting a performance monitor (PM-31), change the Gearbox cover with the
PM-31.
The Gearbox and Transceiver unit (RTR-081) are connected by a waveguide. Install the
Transceiver unit in such a way as to minimize the length of the waveguide for minimizing
the signal loss by the waveguide. And, it has to keep more than specified bent radius
because the loss becomes greater.
