Simultaneous COM performance varies significantly across installations and is affected by both the 
isolation between the COM antennas and the separation of the tuned frequencies. Each installation 
should be individually examined to determine the expected performance of simultaneous COM.

License Requirements 

 

 

The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to 
eliminate radio station license requirements for aircraft and ships. The GIA 6300 installation must 
comply with current transmitter licensing requirements. To find out the specific details on whether a 
particular installation is exempt from licensing, please visit the 

FCC web site

.

If an aircraft license is required, make application for a license on FCC form 404, Application for Aircraft 
Radio Station License. The FCC also has a fax-on-demand service to provide forms by fax. The GIA 6300 
owner accepts all responsibility for obtaining the proper licensing before using the transmitter. 
International transmitter license procedures vary by country. Contact the local spectrum agency for 
license requirements.
