TAPING WHIP ANTENNA
After inserting the whip antenna to the antenna base, 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 15 tape 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.

2. Completely cover the butyl rubber tape with white vinyl tape, wrapping from the base to the
last wind of butyl tape and then back to the base.

width.
2) Squeeze edges of tape with thumb and index finger.
