Dear Karl Thanks for your interest in BigBlue/901i. Following endless quotes and enquiries, with a few installations, some ships travelling worldwide, are quite surprised at how little satellite TV they can receive at sea, once outside of the Ku band satellite footprints. This does not impress clients who have invested $100,000 in entertainment. By designating a home port they can record in real time 840-1200 hours of material for replay in anyway they choose, using only a relatively inexpensive 90cm antenna. I attach the BigBlue/901i spec sheets by way of further explanation. Please telephone if I can be of further assistance.
