3.3.2 Antenna Connector
The 9522B LBT provides a single 50 Ω, SMA type antenna connector both transmit and receive. An
adaptor is available to convert this connector to TNC to enable the 9522B to be used as a replacement
for a 9522A.
3.3.3 GPS Feed-thru Connector
To enable a GPS receiver to share the antenna, the 9522B LBT passes the received signal through to a
50 Ω, SMA type connector. It is intended that this be connected to a GPS receiver. Note that this signal
will not be usable during a call.
3.3.4 SIM Chip Reader
An integrated SIM chip reader is provided on the 9522B LBT. This connector allows installation of the
chip form of the SIM beneath a cover plate on the 9522B LBT housing.
3.4 Mounting
The 9522B LBT incorporates (6) mounting holes on its bottom surface that can aid in its mounting. See
Figure 3 for locations of these features. It is recommended that a thread-forming screw be used to mount
the 9522B LBT via these features. Particularly, a Textron Camcar® Taptite® II Thread-Rolling Fastener of
M3.5x0.6 thread type is recommended. This fastener has a 15IP Torx Plus® pan head and is available in
lengths of 6, 8, 12, 16, and 20 mm as part number 3BE-P802-00, 3BE-P803-00, 3BE-P8185-00, 3BE-
P804-00, 3BEP8186-00, and 3BE-P8187-00 respectively. Length should be chosen to ensure that
penetration into the 9522B LBT housing does not exceed 11 mm. If a 6-32 thread type is desired, a
