Routing and terminating coaxial cable(s)
Plan the coaxial cable route to the wireless device to avoid running adjacent to any existing electrical wiring and ensuring that they
will not be subjected to damage.
The antenna feeds consist of a low frequency element covering 617-960/1710-2700MHz and a high frequency element covering
2.7-6.0GHz. The higher frequency component of all feeds is vertically polarised while the lower frequency component is confi g-
ured with the following polarisations:
Cable 4G/5G A : +45° | Cable 4G/5G B : -45° | Cable 4G/5G C : -45° | Cable 4G/5G D : +45°
Secure the cable run using correct size cable clips, so as not to distort/compress the cable. It is important that the cable is not bent
sharply – note that the minimum bend radius for the cable is 25mm (1") and this should be considered when routing to the cable
entry point. Where the antenna is installed externally, it is good practice to create a 'drip-loop' at the entry point to avoid water
ingress. Any excess cable must not be coiled - it should be laid out in a fi gure of eight pattern and loosely secured.
SMA (m) connectors are fi tted as standard. A 9mm clearance hole is required for the connector – ensure it is not damaged when
inserting through the hole.

Commission and test
Check the comms cables:
•
Carry out VSWR check, the VSWR should measure <2.5:1 in transmit band.
•
Connect the Cellular/LTE cable.
Check GPS cable:
• Check the GPS cable with DC to measure high resistance.
• Connect the GPS cable to the GPS receiver and check for satellite acquisition.
