Weak Satellite signal on some channels - any solutions?

Hi,
I have recently got a satellite and every evening I seem to loose signal on BBC1, 2 , ITV, E4 etc.
Channel 4 and 5 seem fine and a lot of the other channels work perfectly.
For some reason in the evenings, I seem to loose the signal on the main channels.
Any sugggestions? Does this happen to anyone else? Can I do something to strenghten the signal?

Thanks

Re: Weak Satellite signal on some channels - any solutions?

have you looked at the other threads on setting up a dish? Did you set up the dish yourself?

Either your dish is too small, mis-aligned or you need to play with the skew (search this word on the forum) of your LNB.

Re: Weak Satellite signal on some channels - any solutions?

How big is your dish?

Do you have a clean line of sight?

Any cable joins?

Cable quality?

Satellite receiver? (friend recently swopped thier old SKY box with a newer one and due to the better tuner had far better picture quality and some channels that would not work became viewable). The HD boxes also tend to have a better tuner installed.

Hi,

BBC, ITV and the Channel 4 package have the weakest signals on Astra 28.2E (I suppose the better transponders are reserved for Sky).

What that means for you:

- in the Zurich area, you need a dish that's at least 80cm in diameter and it has to be aligned perfectly for the weaker channels to work in bad weather
- you need a decent receiver
- In order to get the best possible signal, make sure you use high-quality cables. Also, the connectors that will let you squeeze the cable underneath windows and doors often lead to signal degradation. Sometimes it helps to simply replace them or to wrap aluminum foil around the unshielded areas.

The reason for the signal degradation in the evening: probably your neighbors WiFi access points, cordless phones and atmospheric conditions etc. When everybody gets home from work, they fire up their wireless home electronics. Unshielded parts of the sat installation are susceptible to em signals in the 2.4ghz area.

Not quite. I think I read this in Greg Dyke's book, "Greg Dyke: Inside Story". After the BBC had an argument with Sky about the price they were charged for the use of Sky's broadcasting services, the BBC moved to another satellite in the Astra cluster. As they were no longer making use of the Sky encryption which was used to ensure that only people in the UK were receiving the signal, the BBC's broadcast was weakened and trained more at the UK.

So it's just a difference in the way that the organisations try to ensure that only UK residents view their broadcasts. Sky by encrypting the signal and making you register with a UK address for the decryption card, enabling them to bombard everywhere with a strong signal. Where as the BBC, ITV, etc have a weaker signal trained on the UK, hoping that those outside the area can't pick up the Free to Air channels.

Cheers

Re: Weak Satellite signal on some channels - any solutions?

I also found properly securing the Satellite stand, made a huge difference. From using old pot plants with rocks to getting nice heavy concrete blocks seems to have improved the signal quality (I think the Sat must have been moving in the wind before).

I don't have problems, but I do have a 90cm wide, 110 tall dish (largest you can isntall withouth building permission), good cables, LNB, new HD box (freesat PVR) and tuned with a good quality meter.

Re: Weak Satellite signal on some channels - any solutions?

Thanks for the tips all...
My dish is 80cms and well secured
And I have a sky+ box, not too old
I've only recently installed the dish so all cables and joints etc are new and seem ok,
Will try and relook at it and see if it works.
Its only certain channels that I lose...BBC, ITV and E4 being the ones that I could do with!

Re: Weak Satellite signal on some channels - any solutions?

In the service menu, you should be able to change the setup/channel that the system uses for the on-screen signal strength. SO you can set this to the BBC channel.

There is a group of saatellites in the sky which make up the Astra cluster. They are close enough that they can be picked up together. If you can focus the dish on the BBC one then you should improve your signal.

I think someone posted all the details in one of the threads here. If you get stuck then maybe someone knows where this thread is.

Or if you get really stuck, I might be able to dopr by with my meter one evening for some beer tokens.

Re: Weak Satellite signal on some channels - any solutions?

This information might help:

http://www.bbc.co.uk/reception/info/...quencies.shtml


1. Press services on your Sky remote control.
2. Highlight option four using the arrow keys and press select.
3. Press (number) 0 then 1 followed by select to access the Installer Menu.

Found in other EF posts:

It looks like ses-astra.com has an error:
Calculated skew/polarity angle on their site is back to front. They seem to suggest that +ve skew is clockwise looking from the satellite to the dish but in reality it is clockwise looking from the dish to the satellite. Following their description my skew was around twenty five degrees out so I got no signal quality at all.

satsig.net has a couple of handy tools:
- find your lat/lon with successive zooms on a clickable map
- accurate calculation for azimuth/elevation/skew from your lat/lon (far more precise than you can achieve with compass and spirit level, but it helps to start-off looking in more or less the right direction)

Re: Weak Satellite signal on some channels - any solutions?

Are the channels always the same ones, which you loose. Did you buy the LNB locally? You could have an LNB that splits the horizontal and verical signals insted of an LNB with gives you all channels.

Another possibility is to use an in line amplifier, which are pretty cheap between the LNB and receiver.

Re: Weak Satellite signal on some channels - any solutions?

amplifiers also boost the noise as well as the signal; if your signal-to-noise ratio is high then you may not see an improvement.
  • Go to the installer menu Services 4, 0, 1 Select (exactly in that order), then go to Manual Installation.
  • Frequency 10773 Horizontal, FEC = 5/6 and Symbol Rate=22.0
  • Then go to the last line then Select, you should then get the signal meters showing you the strength of the 2D channel.
This way you can see what you're pulling in on the BBC channels with regards to Quality
