Sky Q no signal despite good signal

I've had Sky Q a couple of weeks now, previously SkyHD. Dish is 68cm Funke with a Triax TWB104 wideband LNB. Approx 25 meters of WF100 cable. North Yorkshire.

 

Only on the Sky movie channels on 12285MHz V I have intermittent no signal. A reboot fixed it once but it doesn't help now. All connections are tightly screwed. Plugs are crimped on.

 

Signal strength 70, Quality 90. Surely the signal/dish/LNB/cable isn't the issue here? Faulty box perhaps?? Is this a common issue? Or am I missing something.

Are there any other channels on that trasnponxer frequency you can test?

 

The 70/90 thing is on a specific frequency. It's possible others like the one your problem is appearing on are affected by something (usually alignment but can be obstructions) that the test freq is not.

Re: Sky Q no signal despite good signal

It's every channel on that TP. I understand what you're saying about the signal and quality on one TP may not represent the signal and quality of another, but surely one can would assume 70/90 on the default TP is sufficient to give usable signal across the board.

 

I did have one thought. The satellite cables go through two euro modules that also have a TV socket module in the same faceplate. Although all are shielded, is it feasible that the problem TP is being modulated down the cable at a similar frequency to one from Emley Moor? Thus causing it to be knocked out rendered unusable?

hi @Blue.Sky 

 

The Wideband signals share the same band as terrestrial TV frequencies so when using a facepplate they must be fully isolated & not filtered (& of course should never share the same cable)

 

Also a slight misalignement of the dish can lead to some transponders not being as good as others - although I don't which ones are the more likely to show the first signs -apart from the one used by GB News which I know has a different footprint.

 

Please see the chart posted by our kind expert @Godfrey on a different discussion

Re: Sky Q no signal despite good signal

All three euro modules (2x sat + 1x TV) are separate and double screened MK ones. I'm not combining or filtering the signals.

 

The Sky installer seemed happy with the levels from his meter in the house. Connected to fly leads to the wall.

@Blue.Sky  12285 is aEurop wide footprint, and if the dish is slighly misaligned would cause issues.

 

Is this the only channel affected, have you teied these channels too?

Re: Sky Q no signal despite good signal

All those channels are affected and only that transponder. I'm unable to see the signal strength and quality for that transponder as I don't have a meter but wouldn't expect it to be completely unusable if the signal strength and quality on the default TP is 70/90, stable and locked.

@Blue.Sky  Are any of these FTA channels affected also?

No, only the ones on 12285MHz V

Re: Sky Q no signal despite good signal

Thought I'd update the thread as to the cause. Something had chewed through both cables in the garden. Not fully but just enough to stop high frequencies coming through. Hence no issue with low MHz but no signal on the very highest one, 12285MHz .
