ground wire where it lies against the ODU cable. The ground wire must always exit
from the bottom of the wrap.
4. Starting at the bottom, wrap the mastic tape in an overlapping pattern, slightly
stretching the tape as you wrap. By wrapping from the bottom you help to ensure
there are no ridges or pockets for water to sit in.
There must be a full seal of mastic tape onto the pri mary sur-
face for weatherproof ing integri ty.
5. Firm over by hand and squeeze the tape along its edges to form it to the con-
nection. Use tear-off section of the mastic tape backing to protect your hands. Check
that there is no possibility of water entry before proceeding to the next step.
6. Cover the mastic tape with layers of vinyl tape.
7. For a cable ground, wrap from the bottom, with the first layer extending 25mm
(1”) each side of the mastic tape. Subsequent layers must extend no less than 25mm
(1”) each side of the previous layer.
8. Wrap the tape in an overlapping pattern at not less than a half width, slightly
stretching the tape is you wrap, except do not do not stretch for the last two turns of
the top layer to prevent curl-back.
9. Squeeze the completed wrapping to ensure all layers are firm.
To avoid displacement of the mastic tape, do not stretch the
final layer(s) of vinyl tape across sharp corners and edges.
Self Amalgamating Tape
Self amalgamating tape binds to the host and bonds between layers to provide a con-
tinuous seal. It is especially useful in tight locations.
Wrapping Guidelines, Amalgamating Tape
1. Ensure the connectors are firmly hand-tightened, dry, and free from all grease and
dirt. If necessary, clean with a rag lightly moistened with alcohol-based cleaner.
2. Apply the tape with tension (slight stretching), using at least a 75%
overlay.
3. Where possible, apply the tape 25mm (1”) past the ends of the connector barrels
to ensure the weatherproof bond extends beyond the areas requiring protection. The
tape must be applied in such a way that the sealing is robust (no obvious weak
points).
4. To avoid curl-back, do not stretch the tape too tightly at the end.
5. To assist UV protection, a post-wrap using vinyl tape can be applied.
