3.1.2 Choosing a Coaxial Cable

An appropriate coaxial cable is one that matches the impedance of the antenna and receiver being used

(50 ohms), and whose line loss does not exceed 10.0 dB. If the limit is exceeded, excessive signal

degradation occurs and the receiver may not be able to meet its performance specifications. NovAtel

offers a variety of coaxial cables to meet your GNSS antenna interconnection requirements, including:

• 5, 15, or 30 m antenna cables with TNC male connectors on both ends (NovAtel

part numbers C006, C016 and C032 respectively)

• 22 cm interconnect adapter cable between the MCX (OEMV-1/OEMV-1G) or

MMCX (OEMV-2/OEMV-3) and the TNC connectors (NovAtel part #GPS-C002)

Note that a conversion is required between the female MCX connector on the OEMV-1 and OEMV-

1G, the male MMCX connector on the OEMV-2, or the male MMCX connector on the OEMV-3, and

the female TNC connector on NovAtel’s GNSS antennas.

Your local NovAtel dealer can advise you about your specific configuration. If your application

requires the use of cable longer than 30 m, refer to the application note RF Equipment Selection and

Installation on our website at www.novatel.com

, or you can obtain it directly from NovAtel.

High-quality coaxial cables should be used because a mismatch in impedance, possible with lower

quality cable, produces reflections in the cable that increase signal loss. Though it is possible to use

other high-quality antenna cables, the performance specifications of the OEMV family receivers are

warranted only when used with NovAtel-supplied accessories.

3.1.3 Power Supply Requirements

This section contains information on the requirements for the input power to the receiver. See

Appendix A, Technical Specifications starting on Page 129 for more power supply specifications.

WARNING: If the voltage supplied is below the minimum specification, the receiver will

suspend operation. If the voltage supplied is above the maximum specification,

the receiver may be permanently damaged, voiding your warranty.
