Antenna Specifications
The antenna should fulfill the requirements listed in the table below.
The optimum operating frequency will depend on the application. A penta-band (for the GL7500) or
tri-band (for the GL7600) antenna will work in the following frequency bands and should have the
following characteristics.

Note:
Both mechanical and electrical antenna adaptations are key issues in the design of the terminal.
It is strongly recommended to work with an antenna manufacturer to either develop an antenna
adapted to the application or to adapt an existing solution to the application.
