E4 E4+1 More4 C4+1

[Acen]

For some reason E4 E4+1 More4 C4+1 seem to be breaking up early evening.

The dish has not moved (i dont think) and all other channels are fine.

Does any one know is in the summer with the heat, does the signal from the uk get weaker??

The heat must affect the dish some how!!

or is it a case of getting it realined????

Is anyone else having problems???

thanks in advance.

No problems for us on any of the above....sorry!

[Beachcomber]

If your dish is on a concrete platform on the ground it can move because of the earth drying out. If the LNB is several years old it could be failing. If the dish is of inferior quality it can lose its parabolic qualities in the heat.

would anyone reconmend me getting it realined again???

all other channels seem ok.

[Martin Page]

I would like to know too -

Mine has JUST started to do the same with the same channels as well as 2 of the CBS channels and Euronews ...

[Acen]

martin i did not mention it because i dont watch them but for Euronews and the CBS channels mine also break up as well as all the kids pop channels and all the free music channels except Viva and clubland.

The BBC & ITV channels are ok so im grateful enough however it does seem that the picture/signal is deteriorating.

cheers

Just as a matter of interest, what size dish have you got?

[Acen]

1.3m stardard dish that everyone has on the costa.

ive got an titanium twin LNB @ 0.3db as well with a Pace box.

[country boy]

Thanks for the info, We've got a 1.8 so perhaps I should not make observations as we are not comparing like for like.

[markwilding]

I always maintain you should reallign your dish once a year. It only has to be a fraction out to start losing channels.

[El Cid]

Surely it's cheaper to wait until you lose some channels before spending money on realignment?

I have a 1.3m dish in a brick built surround on a very large concrete base. In 7 years it has never needed any adjustment.

[markwilding]

I do my own reallignment. However, Sid is correct. You need to know what you are doing or else you will end up in a worse position than before.

[pietree]

Don´t rush to adjust it, I have read that sun spots can affect it, certainly thick clouds affect even my 3 metre dish.

What coulor card do you have if it´s freeview only?
The blue cards are all switching off by maybe a channel a week and white cards are now required.

Check for nicks along the wire or water getting in perhaps near the LNB,water will short it.

[Beachcomber]

These channels are free to air and do not require a viewing card.

When I checked them on my 1,8 prime focus dish which is set on a concrete slab of about 4 m2 and which has a single output LNB with a noise figure of 0,6dB I had no signal until I adjusted the elevation by an infinitesimal amount (a quarter turn of the adjustment nut) which was imperceptible to the eye but as a result of which I got a signal strength of 75 and signal quality of 70 on an FTE free to air receiver.

As I have said before, I have to adjust the elevation of this dish at least twice a year to take account of the movement of the earth into which the slab, which is about 40cm in depth, is set.

My 1,2 offset dish which is mounted on the garage wall and which has a quad LNB of 0,2dB has never been adjusted and receives these channels with no problem.

If the LNB is more than three or four years old it probably has a fairly high noise figure and after a period of time it will tend to lose sensibility at either end of its range.

As others have said, if you do not feel confident to do so do not meddle with it. The adjustments are critical and are best carried out by someone with the right equipment and necessary knowledge.

...So thats fiddle with it for a bit - then get the guy in to finally adjust it properly again !
Same as last time then .... thanks Beech

So what you are saying Beach is that your house is sliding down the hill

Your dish doesn't need alignment - it needs underpinning!

ill be changing my quad for a twin very shortly so will have to adjust very soon anyway.

I hooked up nilesat yesterday and was watching Top gear on one or the channels in english!!!!

no premier league though

Sid

My house in on flat land but the earth swells when it gets wet and contracts when it dries out resulting in slight movement of the platform. If the dish which is attached to the garage had to be adjusted then I would be concerned but it does not move because the garage, house and other outbuildings are built on huge reinforced concrete platforms to take account of the type of land upon which they are built and the pool has double the usual amount of steel reinforcing for the same reason.

Martin,

I have a Promax Prolink machine but I don't need to use it to adjust the elevation. I just turn the adjustment nut about 45º at a time until I get the optimum signal as shown on the satellite receiver.

[Acen]

on some other forums people have been moaning that the Channel 4 signal has lost its strenghs, this could be a possible reason.
