Lowrance AirMap 2000C Operation Instructions Manual page 21

You may achieve good results by simply placing the external RAA-4
antenna on the top of the dash, at the base of the windshield. Many pi-
lots like to attach the antenna to the top of their instrument panel glare

shields. Depending on the surface, a strip of adhesive Velcro or a piece
of the rubber non-skid shelf liner material available in recreational ve-
hicle supply stores will help hold the antenna in place.
Attach AirMap antenna to windshield bracket with two screws.
We recommend attaching the antenna to your windshield or other win-
dow. For this reason, the remote active antenna packaged with your
AirMap includes a suction-cup mount. Be sure to mount the antenna in
a location where it will not obstruct your view.
Press suction cup plate firmly against a window with unobstructed view.
