1.6.7 Automatic Antenna
Switch AS-102
The AS-102 allows you to connect the an-
tenna to ground remotely when there is a
possibility of lightning, or the antenna must
be grounded to meet with local regulations
when returning to a harbor. Install the switch
between the antenna and the Antenna Cou-
pler. Fasten the unit on a bulkhead with four
5×20 self-tapping screws (supplied), or bolts
and nuts. Coat the ground terminal with sili-
cone sealant. An external switch can be in-
stalled to turn off the antenna manually. See
the interconnection diagram.
