ONNECTIONS
For the best connection, note the following suggestions:
If the connection between the cables will be located outside, we recommend that you use the splice connectors rather than the coupler.
With the splice connectors, there is less chance of the cables separating and also less chance of water reaching the connection. Use the cable cou­pler only if the connection is located inside, protected from the effects of weather and other stresses.
T ry to place the connection between cables inside a building, underneath an eave, or in another location similarly shielded from rain.
The protective shell must be well secured to avoid wind buffeting.
Use hose clamps for poles or conduit clamps for surface mount.
When securing cables, place a cable clip or tie on each side of the protective shell so the movement of the cables does not cause the connection to pull apart.
It is a good practice to leave an extra length of cable near the connection point in case future adjustments or repairs are necessary.

1. Cut the modular connector off the end of the cable.
2. Use a telephone wire stripper or a knife to strip away about 1 (3.8 cm) inches of the black shielding on the cable.
Do not strip away any of the colored shielding on the individual wires. Repeat this procedure for the end of each cable you are connecting.
