iosat are integrators and offer transportable, fixed and maritime mobile satellite communications equipment and services.
Amos 5 satellite coverage area: C band : Orbit position 17deg East. The coverage contours of the Amos 5 satellite are centered on Africa and are shown in the satellite footprint beam map to the right. Larger VSAT antennas may be required in the outer regions of the satellite beam contour.
Please note that ST Engineering iDirect acquired NewTec 1st October 2019, so the link above for NewTec now goes to iDirect.
The two linear planes of polarisation of the receive LNB (horizontal) and transmit BUC (vertical) are at +'-45 deg to the polariser. This produces circular polarisation at the feed horn, which, after reflection and reversal by the reflector, matches AMOS 5 satellite. Circular polarisation is particularly important in the tropics to avoid cross-polarisation interference due to ionospheric faraday rotation.
Some example pictures of typical customer C band VSAT dish antennas are shown on the right, with a detailed view of the feed arrangement used for circular polarisation at C band.
