Cobham Antenna Systems produces antennas with gains from 7dBi to 32dBi, with linear, dual-linear, circular or dual-circular polarisations.
As transmitters, these antennas can tolerate up to 50W input power. As receivers, their system gain-to-noise temperature (G/T) can be calculated, and we can provide all the information relevant to that.
The lower gain, lower frequency, L-band and S-band antennas have very high efficiencies, with low side-lobes, 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, which is especially useful if these are to be used with steering mechanisms.
We have worked closely with Inmarsat to produce a high-gain panel antenna that functions remotely from the Inmarsat Regional BGAN system, which is used for broadband applications around the world, where terrains are hostile or arduous.
