Installing the System on a Pole
The GigaSpire u4hm (GM1028H) can be pole mounted using an optional pole mount kit
from Calix (100-05967). The kit consists of the following components:
Pole Mount Bracket
Bracket Hose Clamp (2)
Ground Lug Cable assembly
Screw, 8-32 x 1/2" Hex Head (4)
To pole mount the GM1028H
Note: The pole mount kit is designed to accommodate a round pole 2 to 6 inches in
diameter. If you have a pole with diameter larger than 6 inches, you can daisy-chain 2
house clamps together for each band (requires 2 additional hose clamps, not supplied by
Calix).
Note: In a pole mount environment, the minimum distance between the u4hm and the
ground is 5 meters (16 feet). Elevation helps APs achieve maximum Wi-Fi coverage per
the system specification. The ideal mounting height above the ground for the u4hm is 5
meters (16 feet). Mounting the unit lower than this height is supported, but it may not
achieve its maximum signal reach. In most environments, mounting the u4hm lower than
5 meters will provide adequate Wi-Fi coverage.
1. Ensure you have a properly buried or secured pole.
2. Fix the pole mount bracket to the pole using the 2 provided hose clamps. The bracket
can be on either left or right side of the pole.
a. Open both hose clamps as shown below.
b. Loop the two hose clamps through the mounting bracket as shown below.
