OEM7 Installation and Operation User Manual v4 25Chapter 2 Installation of OEM7 Family Receiver CardsThis chapter provides instructions and guidelines for checking the contents of the shipping boxand integrating a NovAtel receiver into a GNSS receiver system.2.1 Additional Equipment RequiredFor the receiver to perform optimally, the following additional equipment is required:l Interface for power, communications and other signalsl Enclosure to protect against the environmentl GNSS antenna (for a list of NovAtel GNSS antennas refer to our web site www.nova-tel.com/antennas)l Coaxial cable (and interconnect adapter cable, as necessary)l Data communication equipment capable of serial, USB or Ethernet communicationl Serial, USB or Ethernet data cablel Power supplyl Optional NovAtel OEM7 Development Kit (01019433)OEM7 Development Kit Guide (GM-14915145)When the OEM7 receiver is installed in a permanent location, it should be protectedby a lightning protection device according to local building codes (refer to theLightning Protection Installation and Grounding Procedure on page 14).EmissionsOEM7 receiver products have been designed and tested to meet regulatoryemission limits. Emission levels may be higher for OEM7 receiver card leveloperation than for integrated enclosure level products using an OEM7 receivercard.Refer to Notices Receiver Card on page 12 for more information.2.2 Selecting a GNSS AntennaNovAtel offers a variety of GNSS antennas, including single, dual and triple-frequency, triple-band and wide-band reference antennas (refer to our web site: www.novatel.com/antennas fordetails of available antennas). All antennas include band pass filtering and an LNA. The GNSSantenna chosen depends on the particular application. Each model offers exceptional phase cen-ter stability and a significant measure of immunity against multipath interference. Each antennahas an environmentally sealed radome and all meet the European Union’s Restriction of Haz-ardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE).If a non-NovAtel GNSS antenna is chosen, a typical antenna LNA gain between 26 dB to 30 dB isrecommended in a rover station application.For more information about antenna selection, see Importance of Antenna Selection onpage 225.
