If so please can you tell me why during a rain storm I lose all the terestrial channels via satellite with a message saying No satallite signal received but if I switch over to a Sky channel there is no interference, and if I check the signal meter it is as strong as ever?

Yesterday I missed 95% of the Ireland v France rugby match because it was raining, either the picture disapeared completely or it was pulsing and flashing with the sound coming out like a dalek, surely the sound is not good for the speakers?

Do sky transmit the terrestrial channels with just enough power to be received or what?

Please Sky turn up the power on the terrestrial channels so that they can be received through clouds and rain, if Sky channels can make it through without any problems I am sure you can get the BBC/ITV channels to work the same.

Sky engineer- that is a contradiction.

Obvious problems, are slight misalignment of dish, weak low noise block (LNB), water/faulty in cable, weak tuner in sat receiver (check by swapping for a known good one) groups of programmes come from different transponders with varying power transmission levels

It is not the amount of signal but the quality which is more important, less errors in a good quality signal. Satellite signal is a microwave frequency and are susceptable to loss, due to heavy rain, snow. Not associated with your fault but sun light in the spring autumn equinox can over power the satellite transmission at certain times of day- usually for a few minutes only.

Call sky they will send someone who will swap bits of the setup to find the fault.

Sky don't transmit the terrestrial channels, they just relay them. Transmission power is totally outside their remit, as is the level of service that their third party service providers choose to provision on the transponders. Techically they have either responsibility for nor the ability to correct any of the third party channels except those you pay for as part of the package...

PS I'm not a broadcast or installation engineer but I do have something to do with the relaying of services...

Ok thanks so basically it is the BBC and ITV's fault then! oh well never mind, I can't really complain to them can I as I don't have a TV licence, or infact live in the UK.

Would a bigger dish improve things? I currently have a 60cm dish and all the Sky channels are fine and only during really bad weather do the BBC and ITV channels go **** up, or can you get and inline signal booster that goes between the LNB and the receiver????

If I got a 90cm dish would it help or not make any difference?

Cheers

60cm is more than sufficient, I would check dish alignment as it could be just off which tends not to effect the stronger signals

Hi Steve,

I know it sounds like sloping shoulders, but yes it really is someone else's fault. Though God knows there's enough that Sky do do wrong in other areas...

As for a bigger dish or possible solution, I don't know...but I'll ask someone who does when I get into the office tomorrow,

Have a look here, which may well explain it:

Astra Footprints, Satellite Television, Conrad Anderson UK

You'll probably find that, as the 'terrestrial' channels are only really intended for UK viewing, that they use the Astra 2D satellite with much reduced (UK) footprint. Other broadcasters, Sky etc. can use the others with much wider footprints (Pan-European) as they have a much broader addressible market.

The BBC don't want 'normal' channels received outside of the UK, hence use the VERY UK centric footprint of 2D to achieve this.

I think....

Ah, actually, I've just Googled and confirmed this - BBC does use 2D:

So - Yes, get a BIG dish and/or better LNB and you'll stand a much better chance....

thanks again for all your answers and suggestions.

Steve, most dishes in Portugal are 80cm but I'm told that to receive domestic Beeb channels, I'd need to install a dish of 120cm.

Yeah it is looking like that for here aswell, take a look at MrShades first link it says that I need at least a 90cm dish. Normally my beeb coverages is ok so not really bothered in the past but I may invest in a larger dish for when the RWC is on later this year.

MrShades

LOL....

Sky ''Engineer''

That does make me laugh

Drill a hole in a wall, install a dish, run a cable from the dish to the back of the sky box and tune the tv in and call yourself an engineer within about a days training.

Engineer and technician are to widely used. Proper engineers and technicians get really pissed off, myself included when someone with no engineering/technical skills are labelled as an engineer/technician.

It really makes me wonder some times

That should do the trick, if I can't get good BBC reception with that I may aswell give up

Not sure the neighbours would be to impressed mind

Sbradley

Give the neighbours a free link off it - I think you may get a strong enough signal not to need a booster...

Engineers here concur - you need a bigger chimney wok.

PS Edited to add that they really are engineers here, not installers. Most of them have years and years in broadcast engineering and have brains the size of planets. Including orbiting moons...
