supply longer GNSS antenna cables on request, up to a maximum allowable
length of 50 m (~164 ft) with a maximum signal loss of eight Decibels (dB). It
is not necessary for both cables to be the same length.
1. Install the primary and secondary antennas at the positions you have
chosen and prepared.
Note: Orient the label on the top surface of the secondary antenna
so that it points in approximately the same direction as the label on
the primary antenna.
2. Connect the Threaded-Neill-Concelman (TNC) cable connector to the
GNSS antenna and tighten the connection. Use waterproof tape and
a suitable silicone sealant to protect the connection against the
ingress of water or dirt.
3. Route the antenna cable from the primary antenna to the PCS
mounting location. Avoid subjecting the cable to sharp bends or other
mechanical stresses; minimum bend radius of LMR 400 cable is one
inch (25.4 mm). Use cable clips to secure the cable at regular
intervals along its length. At the PCS mounting location, identify the
cable clearly as the primary antenna.
4. Connect the primary antenna cable to the ANT1 port on the PCS rear
panel.
5. Route the antenna cable from the secondary antenna to the PCS
mounting location. Avoid subjecting the cable to sharp bends or other
mechanical stresses. Use cable clips to secure the cable at regular
intervals along its length. At the PCS mounting location, identify the
cable clearly as the secondary antenna.
