Waterproofing a connector of the RF jumper
(1) Waterproof tape
(2) PVC insulation tape
NOTE
l
Before wrapping waterproof tape, stretch the tape evenly until the width of the tape is half of its original
width.
l
Wrap each layer of tape around the connector tightly and neatly, and ensure that each layer of tape overlaps
more than 50% of the preceding layer.
1.
Wrap each connector with three layers of waterproof tape, from bottom up, then from top
down, and finally from bottom up. Start the wrapping at the position 50 mm (1.97 in.) away
from the bottom of the connector. Do not cut the tape until all the three layers of the tape
are already wrapped. Wrap each layer of tape around the connector tightly.
2.
Wrap each connector with three layers of PVC insulation tape, from bottom up, then from
top down, and finally from bottom up. Start the wrapping at the position 30 mm (1.18 in.)
away from the bottom of the connector. Do not cut the tape until all the three layers of the
tape are already wrapped. Wrap each layer of tape around the connector tightly.
Step 4
