Pre-Installation
Prior to Installation:
• Provision the SMG’s DOCSIS Modem and RF MAC Address. This can include, but is not limited to:
• Assign a cable modem conguration le with the CPE enabled, and the bandwidth set properly.
• Set up a billing account (if applicable)
• Install a power-passing tap on the hard coax.
Required Tools and Materials (User-Supplied):
• Torque Wrench
• 3/8” (10mm) Socket
• 1/2” (13mm) Socket
• 13/16” (21mm) Open-End Wrench
Standard Installation
1. Using the hex head bolts, lock washers, and at washers, secure the strand brackets (PN: 746-627-23-001) to the
SMG (PN: 018-354-20-001), torquing to 44.3 – 53.1 in-lbs (5 – 6 N-m). Verify proper orientation as shown in the
image below.

2. Hang both brackets on the strand through the clamps on the bracket as shown. 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
back of the bracket and tighten the hex head nut, lock washer, and at washer against the clamp on the front of
the bracket, torquing to 79.7 – 88.5 in-lbs (9 – 10 N-m). Repeat for the second bracket.
3. Using the hex head bolts, lock washers, and at washers, secure the strand brackets to the dual antenna module,
torquing to 44.3 – 53.1 in-lbs (5 – 6 N-m).

4. Hang the antenna on the strand about 36” 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
back of the bracket and tighten the hex head nut, lock washer, and at washer against the clamp on the front of
the bracket, torquing to 79.7 – 88.5 in-lbs (9 – 10 N-m). Repeat for the second bracket.
5. Attach the antenna cables to the SMG Antenna ports on one end and to the antenna housing on the other. Torque
connectors to 15 – 20 in-lbs (1.7 – 2.3 N-m).
6. 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).
7. Proceed to the “Start-Up and Verication” section.

Horizontal Installation
1. Attach the GPS Antenna (PN: 670-025-19) to the SMG (PN: 018-354-22-001) using a 13/16” wrench and the
included right angle adapter (PN: 659-014-10) as shown in the image below. Torque to 15 in-lbs (1.7 N-m).
2. Using the hex head bolts, lock washers, and at washers, secure the strand brackets (PN: 746-627-22-001) to the
SMG, torquing to 44.3 – 53.1 in-lbs (5 – 6 N-m). Verify proper orientation as shown in the image below.
3. Hang both brackets on the strand through the clamps on the bracket as shown. 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
back of the bracket and tighten the hex head nut, lock washer, and at washer against the clamp on the front of
the bracket, torquing to 79.7 – 88.5 in-lbs (9 – 10 N-m). Repeat for the second bracket.

strand. Insert the carriage bolt through the bottom of the bracket and tighten the hex head nut, lock washer, and
at 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 Verication” section.
External Dipole Antenna Installation
1. Follow the standard installation steps 1 and 2 for hanging the SMG on the strand.

Start-Up and Verification
1. Connect the powered-coax from the coaxial F connector port to the power-passing tap. When installing the coax
to the F Connector, torque to 35 in-lbs (4.0 N-m).
2. Verify that the unit powers up by looking at the DOCSIS Modem “POWER” LED.
