Hardware Installation of the PinPoint-E
Rev 3.0B Feb.08 33
Figure 4-1: PinPoint-E Connectors
Antennas selected should not exceed a maximum gain of 5 dBi
under standard installation configuration. In more complex
installations (such as those requiring long lengths of cable and/
or multiple connections), it’s imperative that the installer
follow maximum dBi gain guidelines in accordance with the
radio communications regulations of the Federal Communica‐
tions Commission (FCC), Industry Canada, or your country’s
regulatory body (if used outside the US).
Your PinPoint‐E will work with most Dual‐Band PCS cellular
antennas with a TNC or SMA (diversity only) connectors that
work in the high and low frequencies of the cellular
technology of your modem. Connect the primary antenna or
primary RF cable directly to the antenna connector on the back
of the PinPoint‐E.
Tip: When using a cable to an antenna placed away from the
modem, minimize the length of your cable. All gain from a more
advantageous antenna placement can be lost with a long cable to the
modem.
Note: Use of receive diversity for
EV-DO is optional. Data trans-
mission and reception may be
adversely affected if it is not
used.
GPS
Your PinPoint‐E will work with most standard active GPS
antennas. Connect the GPS antenna or cable directly to the
threaded SMA connector.
Mount the GPS Antenna in the vehicle. The less the cable is
wrapped and bound together, the better it will perform. Place
it on the roof, or on the dash, or rear panel where it has a good
view of the sky (greater than a 90 angle view of the sky).
There are three options for antenna mounts:
• Magnetic roof‐mount
• Through glass‐mount
• Permanent mount
To provide for diversity in the signal reception, connect the
second antenna to the second antenna port (SMA, labeled Rx
Div) on the back of the PinPoint‐E.
Caution: If you are not using a diversity antenna, you should disable
the receive diversity option. In Ace Manager in the 1x/EV-DO group,
configure *EVDODIVERSITY.
