Grounding the DU
When the DU is installed outside, electrical (or building) code calls for the outer
conductor of the coaxial cable to be grounded at or near the point of entrance of the
cable into the building. A ground-block is provided with the option outdoor installation
kit.

Drip Loops
While securing the cable outside, ensure that a drip loop is fashioned on both sides of
the ground block and fasten a tie wrap around the loop to keep the loop secured.
Figure 3.3: Drip loops on both sides of ground block
If where the cable enters the building is not next to the ground block, then another drip
loop will also have to fashioned at this point. The drip loop prevents water from collecting
around the cable where it attaches to the block or where it enters the building.
