6. 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.
7. Commission and Test
8. Notices
Check the comms cables:
• Carry out VSWR check, the VSWR should measure <2.5:1
• Connect the Cellular/LTE cables.
Check GPS cable (where applicable):
• Check the GPS cable with DC to measure high resistance.
• Connect the GPS cable to the GPS receiver and check for satellite acquisition.
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 configured 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 figure of eight pattern and loosely secured.
SMA (m) connectors are fitted as standard. A 9mm clearance hole is required for the connector – ensure
it is not damaged when inserting through the hole.
DO NOT
• operate the transmitter when someone is within 1m (3’3”) of the antenna.
• operate the equipment in an explosive atmosphere.
• attempt to install the antennas without the proper safe equipment to access the install location.
• install the antenna near power lines.
• chew parts or put them in mouth, keep away from unsupervised children.
• install the antenna in such a way that it may fall and cause injury.
