I have a motorised 1.8m dish and my 7E Snooker feed is very weak at 1pm but gains strength at 6pm.
The weather is constant so I am at a loss to understand why?
A 1.8m dish in the UK should be getting 7E OK unless it is a very weak signal.
I am getting the snooker feed from 7.0E at 12.0 dB, here today in Surrey with a 1.5m dish.
If you are not locking it easily with a 1.8m dish you have problems with your equipment.
The theoretical dB increase from a 1.5m dish to a 1.8m dish is approximately 1.6dB
If you are located anywhere close to Surrey in the UK you should be getting somewhere around 13.3 dB to 13.5 dB with a 1.8m dish for the snooker feed.
Signal levels based on what I am receiving just before 14:00 UK time today.
