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:
(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)

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

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.

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 72

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.

The DL-V3 enclosure is supplied with a 12V power adapter with a built-in 3 A slow-blow fuse for use
with a standard 12 V DC power outlet. You can choose to press the DL-V3 power button or wait for
the power sequence, when it monitors the serial ports, as long as a valid voltage is present at the power
supply input, see DL-V3 Power Down and the Power Button on Page 33.
