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.

Preparing A8 BTS RF Ports
In order for the butyl rubber layer to tightly seal the RF cable connector-A8 BTS
RF port junctions, the A8 BTS RF ports 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 A8 BTS RF 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-to-A8 BTS connection.
