Taping antenna unit GPA-018S
After inserting the whip antenna to the antenna base of GPA-018S, tape the antenna base
and whip antenna with self-vulcanizing tape and vinyl tape to reinforce the whip antenna.
1. Wrap the antenna junction point with butyl rubber tape No.15 (NITTO SINKO COOP.) or
the equivalent.
How to wrap
1) Pull the tape to be about two times in length and wind it up, overlapping by 1/2 the width
of the tape.
2) Wrap from bottom to top, i.e., from right to left as in the picture below.
3) Wrap the tape from the base to a point about 60 mm, and then back to the base.
Keep tension on edge of tape, using finger to hold tape. Then, squeeze edges of tape
with thumb and index finger.
2. Completely cover the butyl rubber tape with white vinyl tape, wrapping from the base to
the last wind of butyl rubber tape and then back to the base.
How to wrap
1) Being careful not to pull the tape too tightly, wind tape, overlaping by approx. 1/3 of tape
width.
2) Squeeze edges of tape with thumb and index finger.
