ANTENNA
The GlobalNav 310’s antenna can be mounted on any flat surface, pro-
vided you have access behind the surface for the mounting screws. A
magnet is also supplied that can be epoxied to the bottom of the an-
tenna, allowing it to be used on off-road vehicles. A pole mount adapter
lets you mount the antenna on a pole or swivel mount.
ANTENNA INSTALLATION
Surface Mount
The antenna can be easily installed on any flat surface that is at least 90
mm (3 1/2”) wide. Make certain that a clear view of the sky is available at
the selected location. Since the GPS signals travel “line-of-sight”, nearly
anything blocking the antenna can potentially obstruct the unit from find-
ing a satellite.
Once you’ve determined the mounting location, use the template on page
51 in this manual to drill the holes for the screws. The screws, supplied
with the GlobalNav 310, are 4mm x 30mm. (about 1 1/8” long). Drill 4.75
mm (3/16”) holes for the mounting screws. If you route the cable through
the mounting surface, you’ll need to drill a 25 mm (1”) hole for the cable.
There is a notch in the antenna housing that allows the cable to pass
through to the outside, instead of routing it through the mounting surface.
