2.1 External Antenna Connector
Image 3: Optional external antenna port
The TN-202 Compact Flash GPS includes an external port for connecting an active external GPS
antenna for maximum reception of GPS signals. Although the TN-202 has a built-in GPS antenna and
should perform well as is, you may encounter situations where an external antenna would produce
much more favorable results such as when driving downtown among tall buildings, or when the
placement of the PDA unit within the vehicle has a limited or obstructed view to the sky. These types of
situations may warrant the use of an external antenna.
Plug the external antenna with MMCX connector to the plug on TN-202. Place the magnetic external
antenna on the roof of the car (magnet side facedown).
CAUTION:
You must grasp and hold at the antenna connector NOT and put strain on the cable, while you are
connecting or disconnecting the external antenna, as excessive stress to the cable may cause damage
not covered by your limited product warranty.
