The following examples show typical installation methods.
Installation example 1: The pole used has no screw thread tooled. Fix the GPS antenna to the pole
using the hose band and tighten firmly.
Installation example 2 and 3: The pole used is screw threaded (1-14UNS-2A). In a case when the
connecting cable cannot be put through inside the pole, fix the cable at an interval of 30 – 40 cm to the
pole using an appropriate tie (See NOTE).
NOTE: A plastic tie is subject to deterioration caused by ultraviolet ray, etc. Use a stainless tie or
equivalent, having stable characteristic against the harsh marine environment.
