5. RF Antenna Information
This section discusses antennas that are
used with the SeeGull Scanning Receiver
system.
5.1. Antenna Verification
Verify that all the necessary antennas are
included in the shipment and that each is
marked. Each antenna comes in a bag
labeled by
the antenna’s model and its
corresponding frequency range, while the
antenna itself is labeled by frequency range
only.
5.2. Cellular Antennas
PCTEL offers several antennas that are
industry superior antennas supporting low dB
loss cable, extended temperature ranges and
a frequency range wide enough to cover
PCTEL’s SeeGull MX Scanning Receiver.
Figure 9. OP178H and OP278H
The OP178H is a high performance multi-
mode antenna that replaces the OP078H and
OP216 antennas. It supports a wide
frequency range from 698 MHz to 3.0 GHz. It
provides a gain
1
of 3 dBi across the entire
spectrum. These antennas come standard
with a magnetic mounting base and a
male SMA
2
connector for the RF, as
shown in Figure 9 .
The OP278H supports a wide frequency
range from 698 MHz to 3.8 GHz. The
antenna gain is shown in
Figure 10 . The
antenna comes standard with a magnetic
mounting base and a male SMA
2
connector for the RF, as shown in Figure
9 .
The OP279H, as shown in Figure 11 , has
a built-in High Performance GPS base
and a high performance multi-mode
antenna that replaces the OP079H and
OP217H antennas. It supports a wide
frequency range from 698 MHz to 3.0
GHz. It provides a gain
1
of 3 dBi across
the entire spectrum. The antenna comes
standard with a male SMA
2
connector for
the RF and an SMB (push-on/pull-off)
adapter for the GPS.
The OP379H shown in
Figure 11 supports
a wide frequency range from 698 MHz to
3.8 GHz. The antenna gain is shown in
Figure 10 . These antennas come
standard with a male SMA
2
connector for
the RF and an SMB (push-on/pull-off)
adapter for the GPS.
1
dBi gain includes both base and cable losses.
Gain measured on a 3x3 foot ground plane.
