i only have a 80 cm maybe its a 90 cm not sure but if i need a dish as big as a
120cm then theres no way i will be watching TV5 france.I wonder why the little dishes dont work.as long as you have a clear view it should work.All the technology is in the receiver and the lnb. Weather the diameter of the dish is small or large shouldnt make the difference as long as you have a clear view pointing at the satellite.
