The Yagi antenna must be connected to an AP configured with the Hi-Gain matched RoamAbout PC Card.
RoamAbout PC Card Variations
There are two variations of the RoamAbout PC Card: standard and Hi-Gain matched.
The Hi-Gain matched variation of the RoamAbout PC Card is only used when connecting
to a directional antenna in countries that adhere to the European Telecommunications
Standards Institute (ETSI) standards.
All other countries and other configurations use the same standard RoamAbout PC Card.
For example, all countries use the standard RoamAbout PC Card in these configurations:
•
PC Card is not connected to an antenna.
•
PC Card is connected to a 7 dBi omni-directional antenna.
•
PC Card is connected to a vehicle-mount antenna.
Countries that adhere to the Federal Communications Commission (FCC) standards use the
standard RoamAbout PC Card in all configurations.
