5 Antenna Setup
1. Place pilot system bag near the bridge wing door (either port or starboard) and an AC outlet. For
the 210LB/Battery, the DGPS unit is designed to operate outside on the bridge wing, allowing for
a short antenna cable.
2. Locate the Antenna, Cable, and Reel inside the pilot system bag.

3. Clamp the Antenna outside on the bridge wing as far as possible from obstructions. Point the top
of the antenna straight up.
Figure 4: Correct (Left) and Incorrect (Right) Antenna Setup Using Clamp
Note the following when setting up the antenna:
Position the antenna vertically, as shown in the graphic at the left, above. Any other
alignment can adversely affect the antenna’s performance.
Have a good view of the sky. Avoid metal obstructions of any kind.
Be away from sources of electromagnetic radiation, such as radar or radio transmitters.
Be firmly clamped to avoid vibrating out of position.
