Cobham Introduces Antennas for Manned and Robotic Ground Vehicle Data Link Applications

Published: 16 Jan 2012 by

Unmanned AntennasCobham Antenna Systems has introduced a new range of Omni antennas, which have been designed for Manned and Robotic Ground Vehicle data link applications.

The small, rugged antennas have been designed with built-in spring to safeguard operations should the vehicle be constricted for space.

With Single Band or Multi Stacked frequency options, the Omni-Directional antennas have been used for Manned and Unmanned Ground Vehicle communications enabling high data rate communications for video transmissions in applications such as robotic enabled Countermeasures.

Frequency ranges for single band antennas include 3.3 to 3.5GHz and 4.4 to 5.0GHz with other frequency options including multi-band variants are available. Other antenna designs at other frequencies and various feeds are also available with an integrated spring, plus antennas that can be spring mounted.

These types of antenna have been used for COFDM and telemetry applications enabling them to be used in a variety of radio systems for airborne law enforcement downlinks, stationery and mobile tactical links. COFDM provides significant benefits over conventional analogue microwave transmissions, especially in high multi-path environments such as dense urban areas. It is possible to virtually eliminate Fade even in Non Line of Sight situations through the use of spatial antenna diversity systems. COFDM systems are being used for National Security, Police and Military applications where it is vital that video and data links is maintained.

Antennas can be supplied for the other end of the link, such as sector or highly directional variants.

The provision of telemetry of all types from remote sources has become second-nature within all data acquisition systems to enable operators to make advised and sensible solutions.
