4 After the mounting location is determined, disconnect the antenna cable and

install the antenna mounting per instructions provided with the antenna.

Screws and mounting bracket are provided with the antenna.

 WARNING

Before drilling holes through the wall, be sure to determine beforehand the

exact locations of electrical wiring, water pipes, etc. and avoid drilling any

holes which might damage wiring or pipes.

5 The external antenna must be grounded. Figure 13 is a diagram of a typical

grounded external antenna. Additional coax cable, ground lug, grounding

conductor, and grounding clamp are required to ground the antenna. Check

local regulations for specific antenna grounding requirements.

6 Drill a hole through the outside wall and route the cable from the indoor FWT

to the outdoor antenna. Attach the coax cable to the connector on the antenna.

Use appropriate fasteners to secure the cable to the external wall.
