10. Adjust downtilt as desired, per
previous calculations done during
Planning. If any doubts, confirm
downtilt after the radio is operational
using SMs in the field at selected
test locations.

Procedure 3: Cabling and Grounding/Earthing the AP
1. The usual Canopy installation practices apply, including using shielded Ethernet
cable for all infrastructure cabling, using drip loops, providing extra cable for future
use at any termination, and ensuring the tower or structure is fully grounded
(Protective Earth – PE).
2. Use dielectric grease on all connections and in all RJ-45 Ethernet connectors.
(Dielectric grease is generally available in the trade, and is specially formulated so as
to be uniformly non-conducting.) The best practice is to use enough grease to fill the
RJ-45 female connector, and then insert the RJ-45 male connector and push the
grease further into the Canopy unit and around the RJ-45 connector. Excess grease
can be wiped over the connector area to provide some resistance to water ingress
around the connector.
3. Use a 600SSC surge suppressor within 3 ft (~1 m) of the AP, and ground it to known
good ground (Protective Earth - PE) on the tower or support structure with a 10 AWG
ground strap.
A pole mount kit is available for mounting the 600SSC to the tower or mast. The
mount includes a termination point for the ground strap from the 600SSC.
4. Run a 10 AWG ground strap from the grounding lug on the AP (see Figure 9) to
known good ground (Protective Earth - PE) to complete the grounding and protection
of the AP. The termination point on the 600SSC pole mount kit may be used for this.
