You can surface mount the GDL 40 antenna 

), attach it to a standard marine pole 

), or install the antenna under 

fiberglass (

).

To ensure the best reception, keep these 

considerations in mind while selecting a 

mounting location.
•  Mount the antenna in a location that has 

a clear, unobstructed view of the sky in 

all directions.

•  Mount the antenna where it is not 

covered by the superstructure of the boat, 

a radar device, or a mast 

➊

.

•  Higher mounting locations provide better 

reception.

•  Do not install the antenna near sources 

of electromagnetic interference (EMI)

, 

such as the motor or other large marine 

electronics.

•  Install the antenna at least 3 ft. (1 m) 

away from the path of a radar beam or 

VHF radio antenna

 ◦ It is best to install the antenna above 

the path of the radar beam 

➍

.

 ◦ It is acceptable to install the antenna 

under the path of the radar beam

.

•  Install the antenna at least 5.9 in. (15 cm) 

from a magnetic compass to avoid 

interfering with the compass.

1.  Select a mounting location (

2.  Temporarily secure the antenna in the 

selected location.

3.  Test the antenna for correct operation on 

the chartplotter.

4.  If you experience interference with other 

electronics, try a different location.

5. Repeat steps 3 and 4 until you find a 

mounting location where the antenna 

operates correctly.

After you verify correct operation at the 

mounting location, permanently mount the 

antenna.

1.  Select a mounting location for the 

antenna, and verify correct operation at 

the mounting location (

2.  Trim the surface-mount template, 

and make sure the antenna fits in the 

mounting location you selected (

3.  Remove the protective liner on the back 

of the template, and apply the template 

to the mounting location.

4.  Use a

 in. (3.2 mm) bit to drill the 

three pilot holes indicated on the 

template.

 Note: If you are mounting the antenna 

on fiberglass, it is recommended to use 

a countersink bit to drill a clearance 

counterbore through the top gelcoat 

layer (but no deeper). This helps to 

avoid cracking in the gelcoat layer when 

the screws are tightened.

5.  Use a

 in. (10 mm) bit to drill a starter 

hole for the jigsaw blade, as indicated 

on the template.

6.  Use a jigsaw to cut the center hole as 

indicated on the template.
