1.6.7 Automatic Antenna Switch AS-102
The Automatic Antenna Switch AS-102 allows you to connect the antenna to ground
remotely with an external switch 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
unit between the antenna and the Antenna Coupler. When you do not use this unit,
the antenna is connected to ground in the Antenna Coupler by turning off the radio-
telephone.
Fasten the unit on a bulkhead with four 5×20 self-tapping screws (supplied), or bolts
and nuts. Coat the ANT, TX and ground terminal with silicone sealant. An external
switch can be installed to turn off the antenna manually. See the interconnection dia-
gram.
