Antennas
|
|
| The Antenna in the
Pan-Track VMS is built for a combination of GPS and GSM transmission
and reception. Allowing the system to do a larger variety of
tasks
Due to its small size, it is able to
be discreetly hidden within the vehicle un-noticeable to the
eye.
Although the antenna is small, this
does not detract from its powerful capabilities.

- Compact antenna measures only 1 5/8"W
x 2 3/8"L x 5/8"H.
- GPS portion features 5 dBic gain
with 27 dB active amplifier; the Cellular & Trunking
portion typically features 1-2 dBi gain.
- The patented antenna design is an
integral dipole antenna with separate cable for the 800
& 900 MHz portion.
- Double-sided adhesive tape
is used for mounting the antenna in a variety of locations.

Combination GPS antennas are available for frequencies from
141MHz up to 2GHz by simply adding a suitable auxillary 1/4
wave antenna for the required frequency. (For example: GPSK-DE,
GPSK-S1 and GPSK-S2.) |
