5. RF Antenna Information
This section discusses antennas that are
used with the SeeGull EXflex 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 with the antenna’s model number
and its corresponding frequency range,
while the antenna itself is labeled by the
frequency range.
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 EX
flex Scanning
Receiver.
