Abstract

An aircraft in-flight entertainment (IFE) system for an aircraft includes a radome to be carried by the aircraft, and a dual-beam satellite antenna and at least one positioner coupled thereto to be carried by the aircraft and protected by the radome. The dual-beam satellite antenna is to generate dual antenna beams for television programming and Internet data from respective spaced apart satellites. The dual-beam satellite antenna includes a first aperture for receiving the television programming, and a second aperture adjacent the first aperture for receiving the Internet data. A television programming distribution system is to be carried by the aircraft and coupled to the dual-beam satellite antenna to provide television programming within the aircraft. At least one access point is to be carried by the aircraft and coupled to the dual-beam satellite antenna to provide a wireless local area network (WLAN) within the aircraft for the Internet data.
