connections, noise from the amplifier, and possible
ingress of moisture and dust to the in-line amplifier.
In-line amplifier or splitter devices must pass DC
power from the receiver to the antenna, or source the
appropriate voltage and current to the antenna (see
Antenna Specifications). In-line amplifiers may also
over-saturate the receiver front-end if improperly
used.

The antenna cable can degrade signal
quality if incorrectly installed, or the cable
loss exceeds NavCom specifications. Take
care not to kink, stretch, distort, or damage
the antenna cable. Do not place the cable
adjacent to cables carrying electrical power
or radio frequencies. In these instances,
attempt to cross cables at 90º angles in an
effort to reduce cross-coupling of RF
signals.
Where the GNSS antenna is exposed
to sources of electromagnetic
discharge such as lightning, install a
properly grounded in-line electrical
surge suppressor between the GNSS
sensor and antenna. Install protective
devices in compliance with local
regulatory codes and practices.
Protective devices must pass DC
power from the receiver to the
antenna.
