the RF transmission line impedance and frequency range of the UGWAS82. These antennae
may not be modified or altered in any way from the original design as represented in the
antenna datasheets as supplied by the manufacturer.
The antennas selected have been specifically tested with the UGWAS82, and they are certified
through the regulatory agencies in the US, Canada, and European Union for authorized use.
Use of antennas in a platform other than the antennas selected by Unigen voids the MA grant
for that platform.
Antenna Interconnect & Impedance
Unigen has pre-qualified antennas that integrate the connectors, transmission line and the antenna.
UGWAS82 requires the use of a ½ dipole, 2.4~2.5GHz frequency range, with a VSWR no greater
than 2.0 and having a maximum output no greater than +2dBi The transmission line must be
designed to be 50-Ohm impedance.
Physical Implementation
The physical implementation of the RF transmission line must conform to the following
guidelines:
• Coaxial Cable: A coaxial of varying length may be used providing the impedance
measures 50 +/- 2 ohms and is non-radiating. Best practice RF engineering suggests
the cable should be kept to the minimum length required to satisfy the application.
Excessive cable and interconnect loss may adversely effect the effective transmission
and reception range of the end product.
