Multiple purpose antenna system

A multiple purpose antenna system for installation on a highway truck to receive and transmit signals, the system comprising:

• at least one antenna for mobile communication of electromagnetic frequency signals having multiple band widths;
• a multiplex unit coupled to said at least one antenna having circuitry for simultaneously passing multiple signals of band widths below an upper limit;
• and
• a filter unit coupled to said multiplex unit for filtering signals received from the multiplex unit into multiple sets of band width ranges, said sets comprising a first frequency range for use by a first receiver apparatus, a second frequency range for use by a second receiver apparatus, and a third frequency range for use by a third receiver apparatus, and said filter unit being included in a receiver apparatus;
• wherein said filter unit is included within a satellite electronic communications unit that is used by a driver for transmitting and receiving messages to a satellite and from a satellite.
