I have a box in Egypt and have done so for around 9 years now, I first set it up in Dahab with a 3.1 meter mesh dish, I then moved to Cairo and after about a year I changed to a 2.4 meter solid prime focus dish and got the same if not slightly better, so you should be O.K in Sharm with a 2.4 but you will be pushing the friendship and it will have to be spot on as fat as pointing it goes.. As for getting the box into Egypt, it will have to be hand carried in and hope customs don't find it, if they do you will have to pay duty on it .just tell them is a free to air receiver and it shouldn't be too steep if at all, If they find out it can record then that's a whole diffrent kettle of fish. Don't get it sent in by FexEx or what ever as you might not get it and customs will charge you an arm and a leg and will take a very long time to sort out if at all. The biggest dish you are allowed here is 2.4 meters or you might be able to find some 2nd hand bigger mesh ones but as I said, I got more with a smaller solid one. If you find a bigger solid dish can you let me know as I want one too.
Cheers, Robbie.
