If it is desired to use a preamplifier, see below.

preamplifier is powered from the rotator controller.

USING SEPARATE COAX CABLES FOR THE

ANTENNA AND THE ROTATOR

This unit is designed to be capable of using the same coax cable for passing both received VHF/UHF
signals and providing rotator power and control. (See Fig 4)

" Connect the antenna to the drive unit's “TO ANTENNA” jack using a sufficient length of coax cable

to allow for mast rotation (1.25 turns) and a rain-drip loop.

" Connect the drive unit “FROM CONTROLLER” jack to the indoor controller via the main coax

downlead.

Using A Preamplifier Or Amplified Antenna

" Only a suitable preamplifer designed for powering by +17 VDC at less than 50mA may be inserted

between the antenna and drive unit's “TO ANTENNA” jack. Contact Pro Brand for a suitable
preamplifier.
