Fasteners should be weather and UV resistant.
Cables should have some slack for thermal expansion/contraction between fastenings.
An 80cm cable (supplied with GPS antenna kit) connects the GPS directly to the AirSynergy
connecter, on the bottom panel. When mounting the GPS antenna remotely from the unit, the
GPS antenna should be used in conjunction with the Remote GPS Antenna Mounting Bracket
(supplied with the GPS antenna kit) and the appropriate length GPS cable RG58 TNC-TNC by
way of TNC connectors.
Note:
All cables should be properly secured to prevent undue strain on any of
the cable terminations.
Note:
AirSynergy units without a factory assembled Switched Beam Antenna all
require a GPS antenna (unless an alternative synchronization method is used,
such as IEEE1588-2008) which comes in a kit with a mounting bracket and a
80cm cable. A primary consideration for a GPS antenna is a clear view of the sky,
preferably 360 degrees.
1. Assemble the GPS antenna to the mounting bracket supplied in the GPS antenna
mounting kit. The large nut should be tightened with a pipe wrench.
Caution:
Take care not to over tighten the nut so as not to damage the plastic
threads.

2. Attach the TNC to TNC cable from the GPS antenna to the TNC connecter on the bottom
of the AirSynergy unit.
Note:
For extreme weather conditions weather-proofing of the TNC connections
is recommended. This is done with a layer of self-amalgamating tape followed by
an over layer of PVC tape. The weather-proofing is best done at this stage to give
easier access to the connections.
3. Attach the GPS antenna assembly to the body of the AirSynergy unit using the single M6
screw and lock washer provided in the kit. There is a threaded hole on the top corner of
the AirSynergy unit for this purpose.
