NSTALLING THE 
A
NTENNA
Both the input DC power and the output RF signal use a single coaxial cable connected to the antenna's 
TNC female connector.
The antenna attaches to a surface with an ARINC-743 bolt pattern. Four screws pass through the antenna 
housing.
To install the antenna:
1. Install the supplied o-ring into the groove on the antenna base.
2. Predrill the mounting holes and the connector clearance hole on the mounting surface. See the 
Mechanical Drawings section for mounting pattern details.
3. Use the four supplied mounting screws to attach the antenna to the mounting surface. The o-ring com-
presses and creates a seal between the surface and the antenna.
User supplied o-ring grease can be used to hold the o-ring in the groove during installation.
NovAtel recommends thread-locker (not included) on the mounting screws.
