Step 4: Connect the GA 31 Antenna to the GDL 30/30A

Since antenna mounting locations and methods vary, you will need to obtain an antenna mount to install

the antenna. The antenna base ﬁ ts a standard 1-inch, 14 threads-per-inch marine mount. Check with your

Garmin dealer or a marine supply retailer for this item.

Temporarily place the antenna at your desired installation location. Then, check its operation with poten-

tial interfering equipment turned on and off. (For example, other electronic equipment, fan motors, engine

ignition, alternators, generators, radars, and VHF radio transmissions can be sources of interference.)

Position the antenna so that it obtains the clearest possible view of the sky and horizon in all directions.

Avoid mounting the antenna next to large areas of conductive material (such as metal and aluminum) as this

may cause poor signal reception. The GA 31 antenna is supplied with a 30-foot cable. When routing the

cable, avoid routing it near the vessel' s alternator or ignition system components or parallel to other power

lines. Do not cut or shorten the cable; doing so can harm the weather and radio reception.

After you have found a suitable location, permanently install the antenna. Then, connect the antenna cable

to the GDL 30/30A connector that is labelled ANTENNA.

If you have a GDL 30A: Connect the Audio cable (included) to the GDL 30/30A connector that is

labelled AUDIO and to the audio inputs on your stereo receiver.

Step 5: Turn on the GDL 30/30A

Once you connect the GDL 30/30A to your boat' s power supply and to a Chartplotter (either directly or

via a Garmin GMS 10 Network Port Expander), the GDL 30/30A automatically turns on or off whenever you

turn on/off a Chartplotter.

Turn on your Chartplotter. Check the blinking lights on the front of the GDL 30/30A to ensure that it is

on (see Appendix A to view the blink codes).
