Direct Wave Satellite Antenna Systems

 

Aircraft Satellite Antenna Systems

Anderson Aerospace LLC has developed a new compact microwave antenna technology that offers improvements over existing satellite television and broadband communications systems for aircraft in flight.  Our Direct Wave technology’s smaller size significantly reduces weight and operating costs due to reduced drag.  In addition, Direct Wave technology produces microwave antenna systems that are less costly, more reliable and more efficient than existing systems.  These developments collectively provide a game-changing competitive advantage.

 

Drag Is Costly

A fuselage mounted antenna system can be costly for the aircraft operator. Fuselage radome sizes range from 60 to 90 inches long, 30 to 48 inches wide, and eight to 15 inches tall.  A large dorsal radome can increase drag by more than 4%.  The solution?  A compact antenna mounted in the tail.  The resulting fuel savings can be up to $180,000/year on a 130-seat aircraft.  If the aircraft can’t accommodate a tail installation, a compact antenna mounted on the fuselage still reduces drag by 65%, saving the operator as much as $117,000/year.

 

Suitable For Both Tail And Fuselage Mount

Compact Direct Wave Antennas can be mounted on the tail for maximum drag reduction or on the fuselage for up to 65% less drag versus typical fuselage installations.  Direct Wave fuselage installation provides lower drag and less weight while reducing radome costs.  Multiple antennas can be installed with no additional drag.
