Installing GPS Line Amplifiers
The allowed length of a cable is limited depending on the GPS cable
configuration. You must compensate for the loss by installing a line amplifier if
the cable exceeds the length allowed. Because the required number of line
amplifiers and installation method may vary depending on the extended length of
the LMR-400 cable and line amplifier specifications, you must refer to the
installation instructions provided with the line amplifier.
In addition, you must install the line amplifier within 32.8 ft. (10 m) from the GPS
antenna.
Line Amplifier Usage Guideline for GPS Cable Configuration
The total length of the LMR-400 cable should be no longer than 328.08 ft.
(100 m).
