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.
1.
Cut the butyl rubber tape into 1/5” (5mm) by 4” (100mm) strips.
2.
Wrap a strip of butyl rubber tape around the base of each antenna port in the clockwise
direction. Take extra care to make sure that the resulting butyl rubber ring would not hinder
the tightening of the RF cable connector around the antenna port.
