I contacted London SatMan to help with problems with the signal to my Humax box which had been installed a few years earlier by someone else. The signal had been intermittent and unreliable and then dropped out completely. Walter responded to my emails very quickly and arranged to come and inspect my aerial/dish after checking that there were no obvious issues. He is very knowledgeable, professional and basically a nice person to deal with. Walter also advised me beforehand of his costs and possible expenses I might have to incur (depending on what the fault was) which I found reassuring. Not only did Walter fix my problem but he improved the signal I was getting on my box. Highly recommended.
