Cable-Based Antennas Aid Airborne Wireless

A new line of cable-based antennas, also known as leaky feeder lines, has been developed to simplify the installation of airplane-based wireless communications systems. Ideal for both wide-body and single-aisle passenger aircraft, GORE® Cable-Based Antennas provide reliable access to different wireless protocols. They are easily installed along the length of the cabin

ceiling. With signal propagation occurring every meter along the antenna, passengers are assured reliable access, regardless of their location in the cabin. The leaky antennas support frequencies from 0.4 to 6.0 GHz for a wide range of wireless standards, including Bluetooth, DECT, DECT2, Global Star, GSM, IRIDIUM satellite communications (satcom), MMS, PDC, TETRA, UMTS, WLAN 802.11 a/b/g, and WiMAX. Available in lengths of more than 65 m, they require no maintenance for the lifetime of the aircraft. They meet all applicable aircraft shock, vibration, and fire specifications, including AirBus ABD0031 and FAR Part 25.1359(d).
