Freesat Issue?

Frank99

Recently had a new freesat dish with lnb installed by an electrical shop to replace old Sky dish which was losing signal, the channels are all good signal and working well after installation however, i now noticed NHK World, Sporty Stuff TV , RT UK and CNBC to a lesser extent are suffering awful pixilation and most often no signal which makes them unwatchable, all other channels seem fine though.

Is their anything i can do at my end before contacting the company, I know very little about this subject.

Not a lot no, to improve signal strength to some channels you need to increase the size of the dish.

Freesat isn't great, I have both but I prefer freeview using the tv aerial.

Do you have any trees or other similar obstructions in line-of-sight between your dish and the satellite?  If not, definitely call the installers back and ask them to adjust the dish so that it gives maximum signal strength and quality.

Call installers back under guarantee.

No reason for any channels of freesat epg to pixellate if:

• Correct dish size chosen for the location
• Decent quality all-copper satellite grade cable used for the length installed (the correct 100 rather than 65 to minimise cable loss at higher frequencies, longer lengths)
• All terminations done properly and weatherproofed externally with boots or self-amalgamating tape.
• Dish aligned and lnb skew set correctly using a professional-grade meter.

NHK World & RT UK are on 11.226 GHz, Vertical
Sporty Stuff TV is on 11.538 GHz, V
CNBC is on 11.479 GHz, V in sd 
They are all vertical polarisation and in the higher end of Lo band frequencies (switching lo to hi is at 11.70 GHz).
CNBC HD is 12.168 GHz, V so hi band and again vertical.

My money's on carp thin shotgun cable compounded by poor skew setup.
