13.9.12 Antenna Connection Weatherproofing
Where a cable connects to an antenna or unit from above, a drip loop should be left to ensure
that water is not constantly channeled towards the connector.
Figure 89 - Forming a Drip Loop
All joints should be weatherproofed using self-amalgamating tape. It is recommended that a
layer of PVC tape be placed over the self-amalgamating tape to protect the joint while the
self-amalgamating tape cures and give additional protection.
Figure 90 shows this
diagrammatically for the Connectorized version of the PTP 400 Series bridge unit end of the
antenna cables. If the antenna manufacturer has not supplied guidance on this matter the
same technique should be employed at the antenna end of the cables.
