2.3 External Dipole Antenna Installation Procedure
1. Follow the standard installation steps 1 and 2 for hanging the SMG on the strand.
2. Attach each external dipole antenna to a strand mount bracket (
PN: 746-627-31-001
) using the included
hardware, as shown below. Torque to 79.7 – 88.5 in-lbs (9 – 10 N-m).

3. With each antenna secured, hang the brackets on the strand at about 36” and 60” away from the ports on the side
of the SMG. For thicker 3/8” strands, reverse the orientation of the clamp so that the larger concave side faces the
strand. Insert the carriage bolt through the bottom of the bracket and tighten the hex head nut, lock washer, and
flat washer against the clamp on the top of the bracket, torquing to 79.7 – 88.5 in-lbs (9 – 10 N-m). Repeat for the
second bracket.
4. Attach the antenna cables to the SMG Antenna ports on one end and to each antenna on the other. Torque
connectors to 15 – 20 in-lbs (1.7 – 2.3 N-m).

5. Properly ground the SMG by connecting a #6 AWG wire from the grounding lug on the outside of the enclosure
to either a driven ground rod or the strand ground on the pole to which the unit is mounted. Apply anti-oxidant
compound (e.g. Noalox® or equivalent) to the ground connection. Torque to 44.3 in-lbs (5 N-m).
6. Proceed to the “Start-Up and Verification” section.
