antenna enclosure, and is not in the microwave beam.
Transmitter/Receiver
Mount the transmitter and receiver units on their respective posts, using the pipe clamps and hardware provided.
The mounting height of the transmitter and receiver units is measured from the center of the antenna to ground.
Refer to Determining mounting height on page 3-6 for the approximate mounting height of the microwave units.

Transmitter/Receiver grounding
Connect a ground wire(s) to a properly installed ground rod. Connect the ground wire(s) to the appropriate
terminal(s) on the Transmitter/Receiver PCB. (Refer to Figures 3-4 and 3-5 for wiring diagrams of the Transmitter
and Receiver circuitry.)

NOTE: Senstar-Stellar recommends using a low resistance (5
Ω
or less) earth ground
connection at each unit. Consult the local electrical codes for additional
grounding information.
grounding information.
Conduit
1.3 cm (1/2 in.) flexible conduit should be used to run connections to and from the transmitter/receiver units and
power supply junction box. Allow enough slack in this flexible conduit to provide a “drip loop” and vertical
movement of ± 46 cm (18 in.).

NOTE: Conduit and conduit fittings are not included.
Align head-to-head
Physically point the transmitter and receiver toward each other and slightly tighten the clamp nuts so the units will
not fall. Loosen the two nuts on either end of the bracket, and aim the units (in the pitch axis) toward each other.
Slightly tighten the two nuts.

Slightly tighten the two nuts.
NOTE: This is a preliminary mechanical alignment only. A more precise electrical
alignment will be accomplished as part of the Operating instructions procedure.
Optional wall mounting
NOTE: When using the optional wall mount bracket, disregard references to post
mounting, and follow these instructions.
