ACX500 GNSS Antenna Surge Protection

Antenna Installation Verification

94
NOTE: ACX500 GNSS output current supports only 3 V antenna voltage,
which work with maximum current and supports voltage tolerance as
calculated in Table 37 on page
For antennas that do not have a voltage rating of 3 V DC, we recommend
that you use an active splitter or amplifier as required (DC block from ACX500
and antenna power from external power source) that supports the antenna
voltage.
For a roof antenna, we recommend that you provide additional surge protection in
accordance to the regulations and standards for lightning protection in the country where
the ACX500 router is installed.
NOTE: We recommend that you use an external first-level fast lightning
protector that has clamping voltages of 15 V and 20 V.
WARNING: Make sure that grounding is available and that it meets local and
national electrical codes. For additional lightning protection, use lightning
rods, lightning arrestors, or surge suppressors.
After installing the GNSS antenna, verify that the installation is properly done:
Verify that all the cables and connectors are installed correctly and securely fastened.
Ensure that all connectors have been protected from weather by using the latest RF
cabling installation and protection guidelines.
Verify that the GNSS antenna interface status is good in the respective GPS monitoring
application. Also, verify the status of the
Verify that the cable service loop or the drip loop is utilized and is sufficient.
Unlike other radio device, do not apply any tape or chemical protection to the
connectors. The recommended connectors are weatherproof, and adding any
protection makes the warranty void and can lead to expensive repairs.
