Satellite dish and conservatory

I have a sky digital setup in the UK.

I am having problems with my dish when I am trying to view INI on
transponder 11.662/H Sky channel 767.

The dish is located over a polycarbonate conservatory roof. If I line
up the dish to wnable this channel to be received, I find a few hours
later the channel is no longer available. (Sky box says that there is
no satellite signal being received).

I have found that if I now open my kitchen door to the conservatory
(This door being directly below the dish), I find that the channel
becomes available again..It seems that the door is acting like some
sort of aerial!!

The dish is located near the first floor bedroom window...

Does anyone have any explanation for this behaviour?

Yes, I have a similar problem.....

If I am watching Bloomberg and the kids go in the bath I lose this channel.
If however they take a duck in the bath with them the channel remains.
Weird init !!!?? : ((

If I understand correctly - you mean the OP is talking bollox :-)

Presumably the house is rigid? You aren't in a chalet-type building?

Or the cable is stuck between the door :-)

This problem makes no sense to me either....!!!

The house if stand solid brick construction, and the cable does not go
thro the door, it enters the roof space and then thro the wall to the
lounge

Could there be a multiple reflection somehow putting thermal noise / ground
noise in the path of the dish? Perhaps you should try moving the dish
somewhere else, where it could not be affected by what's going on in the
conservatory beneath it. Polycarbonate is transparent at satellite
frequencies, and has dielectric properties which might conceivably cause
some kind of reflection or refraction.

What do you mean "to enable this channel to be received"? How is the
reception of the other 200+ FTA and FTV channels?
A correctly aligned dish gets all the channels, all the time. You
NEVER have to adjust it to get one specific channel and if you are
doing so then your installation is all wrong.

I wonder if you haven't incorrectly aligned your dish to receive some
reflection instead of the main beam?
I had a similar problem once with a motorised dish. All set up nicely
for about 5 different birds but I could only get high band channels on
28E. I fooled about for ages with it and then realised that the moving
dish was in fact going past 28E and pointing at a nearby wall and not
at the satellite at all. There was a strong enough reflection off the
wall to bring in the high band channels but not enough for the low
band ones. Once adjusted correctly it worked fine.

Only the truth as I see it.
No monies return'd. ;-)

If you check on transponder 11.662/H you will see that there are only
about 5 channels. they are all obscure channels which most poeple would
not watch.
for some reason this transponder see either to be transmitting weak or
on a tight beam, so all other channels seen to work fine, but I need to
be vey picky in trying to align the dish to receive this particular
transponder...

This is the top channel on low band H. Here in the north of England on a
standard Sky dish and LNB it appears to be about 2dB (which is a lot) below
its neighbours, but still has a just tolerable BER of 3.8 E-3, when received
as a low band channel. However, the particular LNB I've just tried performs
better if the transponder is received as high band, in which case the BER is
5.5 E-4, which is a lot better. This is possible on test gear but I can't
imagine that a Skybox would do it.

Strange things happen with LNBs at the very edges of their frequency range.
A different LNB might be the answer.

The channels on the transponder suggest that you are either a Muslim, a
Chinaman, an enthusiast for some of the more extrovert forms of
Christianity, or a gambling addict. Or, I suppose, a combination of any of
these. I'm curious.
