2.10 Connecting the Antenna to the Receiver Card
An interconnect adapter cable is required to convert the end of the antenna coaxial cable to the
RF input connector on the OEM7 receiver.

For the location of the antenna connector on the receiver card, see Figure 9: OEM719 Connector
and Indicator Locations on page29, Figure 10: OEM729 Connector and Indicator Locations on
page30 or Figure 11: OEM7700 Connector and Indicator Locations on the previous page.
NovAtel generally uses the MMBX connectors with barrels for board-to-board
mounting. These connectors allow a blind mate and are able to move slightly under
vibration to reduce the potential for damage to either PCB. The mating connector
on the interface PCB must be a Huber and Suhner 82_MMBX-S50-0-1/111 NE or sim-

2.10.1 Antenna LNA Power
NovAtel antennas and coaxial cables meet receiver RF input gain requirements. NovAtel anten-
nas are equipped with built-in LNAs that provide 26 dB of gain to the satellite signal received.
The power to the antenna LNA is provided through the receiver’s RF port center conductor. To
achieve the required input gain to the receiver, NovAtel coaxial cables are designed to introduce
no more than 10 dB loss. Antenna supply over current protection limits the LNA power.
OEM7 receivers provide +5 VDC ±5% at a maximum of 200 mA.
