Installation Tips

A few general rules about weatherproofing RF ports:

1. Always apply tape at temperature above 32 degrees F to ensure

adhesion. When working in cold weather, always protect your tape

rolls by storing it under your coat and next to your body to keep

tape flexible. If the tape cannot stretch elastically, it will not seal

properly.

2. Do not stretch the tape to the point where it distorts. Only apply

enough pressure to get a smooth wrap.

3. Smooth each wrapped layer of tape with your hands to ensure

proper adhesion.

4. Do not pull the tape to tear it - always cut the tape. A pulled tape

will most likely unravel, decreasing protection.

5. In warm climates where there will be long exposure to sunlight, it is a

good idea to wrap an extra layer or two of electrical plastic tape

over the butyl rubber layer to enhance UV protection.

6. For vertical runs of cable, the final layer of electrical tape should be

wrapped from the bottom to the top, and overlap about 50% of the

width of the tape. This will provide the same effect as shingles on a

house. The water will run down across the joints without going into

the joints.

In order to properly weatherproof of the BTS radio antenna ports, they

must be prepared before the installation.
