When planning to install an outdoor external antenna:

•

Locate the antenna on the external wall of the building.

•

Keep the outdoor external antenna as close as possible to 
the base station serving it. The base station itself must be 
indoors. The recommended mounting height is 13 ft to 
16 ft above ground.

•

Always install a lightning surge arrestor between an 
outdoor antenna and a base station. 

To install an outdoor external antenna, follow these steps:

1. Drill a hole for the coaxial cable.

2. Install conduit for the antenna cable according to local 

building and wiring codes.

3. Screw the antenna bracket to the wall so that the antenna is 

positioned vertically on the exterior wall of the building.

4. Loosen the nut on the antenna. 

5. Slide the antenna into the slot of the bracket and tighten the 

nut.

6. Feed the coaxial cable through the wall to the lightning 

surge arrestor on the interior wall.
