The ACU’s four-foot whip antenna should be mounted as high as conveniently possible—but not at the highest point—and as far away as possible from other antennas.

    SECTION TWO - Installing the unit ble-free installation; however, the installer may want to adjust these distances, depending on the particular equipment and how it’s config- ured. Because each installation is unique—according to the wishes of the customer—this information should be used only as a guideline. It isn’t absolute in determining the best location for every possible equipment configuration.

  • Page 27: Figure 7: Gps-Only Antenna (An150)

    SECTION TWO - Installing the unit high as possible: Values of 15 and higher are preferable, and anything below 10 could indicate poor reception. NOTE: Concerns for the AN205-P that aren’t explained in Table 3, “Troubleshooting the GPS/DGPS antenna installation,” on page 35, include the fact that mounting a loop-type antenna in close proximity to a radome (radar-set antenna) can degrade signals or cause a complete loss of the beacon signal.

CAUTION! The GPS-only antenna must be used with a minimum of 20 feet of cable, and no more than 100 feet.

If you have several possible antenna locations, you may evaluate each by operating the unit with the DGPS antenna temporarily mounted in each location.
  • Page 37 SECTION TWO - Installing the unit Another major concern, precipitation static (called “P-static”), must be addressed when installing the differential antenna. P-static generally appears only during rain or snow; consequently, it can easily be over- looked during installation. Much like a loran antenna, the effects of P-static are minimized if the differential antenna is mounted so that it isn’t the highest metallic object on the vessel.
