Mickat the size of dish has been a long debated issue, i fitted a 1.9m over 10 years ago and have had constant free to view tv, people have sold mesh dishes, tri dishes, 80cm 1m 1.1,1.2 etc all have failed to provide a signal at some point due to the location being near the edge of the signal footprint, with the recent new astra signal you can receive a signal again with a smaller dish, How long is the question ?
