Mounting - Furuno GP-310B Installation Manual

1. MOUNTING

Mounting considerations
When selecting a mounting location for the antenna unit keeps in mind the following points.
The antenna may be mounted three ways: screwed into a pipe (local supply), fixed to a
post with the optional mast mounting kit, or screwed into an optional mounting base. For
fixing by the post or pipe, it is recommended to use stays to prevent damage to the GPS
receiver.
Select a location out of the radar beam. The radar beam will obstruct or prevent reception
of the GPS satellite signal.
The location should be well away from a VHF antenna. A GPS receiver is interfered by a
harmonic wave of a VHF antenna.
The location should be well away from an Inmarsat-B antenna. Transmission of
Inmarsat-B will obstruct or prevent reception of the GPS satellite signal.
There should be no interfering object within the line-of-sight to the satellites. Objects
within line-of-sight to a satellite, for example, a mast may block reception or prolong
acquisition time.
Mount the antenna unit as high as possible. Mounting the antenna unit as high as
possible keeps it free of interfering objects and water spray, which can interrupt reception
of GPS satellite signal if the water freezes.
If the antenna cable is to be passed through a hole which is not large enough to pass the
connector, you may cut the cable with cutting pliers. Re-connect it after running the cable
through the hole. Wrap cable with vulcanizing tape and then vinyl tape. Bind the tape end
with cable-tie.
Mounting
Install the antenna unit by referring to installation diagram of page D-1.
