I was recently contacted by the Ashford International Hotel.
They have a twin screen Sky HD set-up in their sports bar, and it was becoming a very poor viewing experience for their customers; with a blocking and freezing picture.
Upon checking the signal quality and strength with my meter, it was low and fluctuating.
I made my way up to the roof where the 15yr old dish was sited and checked the signal at source. All seemed OK, and the dish was aligned 100%. I did try another LNB, which did give me more signal from the dish (which was in surprisingly great condition considering it’s age), and changed the connector for one that eliminates signal egress and the ingress of interference.
Back at the Sky HD box, I removed a non-shielded socket and replaced with a straight through connection by using some more connectors.
When checking the signal for a second time at the back of the Sky HD box, we were looking in spec with the quality and strength, and it was stable with zero fluctuation.
When reconnected, the TV picture looked great. And considering that this was on the 5th June at the exact time of a massive downpour and thunder storm, that was fantastic to see!
Since that day there have been no further reported issues, so whether it was something within the hotel that was interfering or just low signal at the box after it had been attenuated over the massive cable run. All is now fixed, and happy customers will be once more.
