Hi Andy,

I have used the same Hughes 9101 terminal on both systems.

The polarisation is different - one is LH circular and the other one RH circular

There is a big screwhead slot thingie on the back of the flat plate antenna in the lid which you have to change over...

Subjectively the Thuraya system seemed faster but needed a higher S meter reading than when using the Inmarsat satellites.

Hope this helps

where are the difference between Inmarsat and Thuraya satellite sytem, frequency and mode etc. or this is the same system.
