Before you begin, refer to Installing the cellular module  for information about the installation type 
you are performing. All of the parts you require to mount the antenna cable are included in the 
cellular module kit.

To mount the antenna, perform the following steps:
1. Drill or punch a 21/64 inch (8.3344 mm) hole in the unit. If you are mounting the antenna on the

external box, use knockouts instead.

2. Remove the nut from the SMA connector, leaving the lock washer in place.
3. Place the lower, thicker nylon shoulder washer on top of the lock washer, with the collar side

facing up, see Figure 6.

4. Insert the SMA connector through the hole from the inside of the unit.
5. Place the second, thinner nylon washer over the SMA connector.
6. Replace the nut and tighten firmly, so that the cable does not spin freely.
7. Connect either the antenna or the extension cable to the SMA connector.
8. Route the antenna cable through the unit as power-limited wiring to the cellular module on the

CSGM.

Note: The primary antenna connects to the cellular module at J4. The secondary antenna connects to the 

cellular module at J3.

9. Press the antenna cable MMCX connector firmly to the connection on the cellular module until it

snaps into place.
