Installation

Remote GPS Antenna

The GPSCOM 190 includes a GARMIN GA 27

remote GPS antenna which can be used to enhance satel

lite reception. Simply plug the “MCX” male connector on

the end of the GA 27 cable into the socket located on the
side of the GPSCOM 190. Place the antenna in view of
satellites, and the system is ready for operation, The
GA 27 can be mounted using the suction cup mount,
w^hich is included with the antenna. When mounting,
you must ensure that the antenna’s location provides an
unobstructed view of much of the sky This is critical to
allow the antenna to “see” at least four satellites in order
to compute your position and track your flight.

To use the suction cup mount:

Attach the suction cup mount to the bottom of the GA 27

antenna using the two flat head screws (provided).
Position the antenna as low as possible on the wind
shield to maximize satellite visibility and not obstruct

your view of the sky.

The suction cup mount can be adjusted to compensate

for aircraft windshields of varying angles. The adjust

ment is made by rotating the large suction cup until the
proper angle for mounting is obtained.
