Cobham Antenna Systems produces antennas with gains from 7dBi to 32dBi, with linear, dual linear, circular or dual circular polarisations.
For transmit purposes these antennas can tolerate up to 50W input power and for RECEIVE, we can provide information for system gain-to-noise-temperature (G/T) to be calculated.
The lower gain, lower frequency L-band and S-band antennas have very high efficiencies and low sidelobes which provide for optimum G/T.
Modest gain C-band and X-band flat panel antennas can replace small parabolic dishes and horns providing a very low profile, especially if these are to be used with steering mechanisms.
We have worked closely with Inmarsat to produce a high gain panel antenna to work remotely from the Inmarsat Regional BGAN system, used for broadband applications around the world where terrains are hostile or arduous.
