Routing and terminating coaxial cable(s)
Connect the extension coaxial cables to the antenna and route the cables to
the radio equipment.
When routing the cables take care to avoid running them adjacent to
any existing vehicle wiring or fouling any moving vehicle components.
The c ables must not be routed in front of any airbag device. Fit the
correct coaxial connectors or adapters to the cables as required. If
extension cables are needed please contact your retailer.
Commission and test
Check the comms cables:
• Earth continuity: connector body to vehicle ground should measure <0.2Ω
(where applicable).
• For LTE elements connector body to centre pin should measure low
resistance (elements are DC grounded). WiFi elements should measure open
circuit using the same test.
• Carry out VSWR check – the VSWR on all feeds should meet the
specification in product data sheet.
• Connect the Cellular/LTE and WiFi cables (if applicable) or secure
unused pigtails.
RF Safety Note – Ensure that the antenna is mounted in such a way that
no person is likely to be within a distance of 30cms (12”) from the
antenna during use. Ensure that the antenna is used only as supplied.
The co-axial cables should not be cut shorter or otherwise modified.
General Safety Note – Make sure that the product is mounted so
