Mr Thompson:
You say you have two dishes. Have you got planning permission to have two fitted? See Planning Permission: Houses and buildings up to 15 metres high | Satellite,TV and radio antenna | Planning Portal for details. If you already have an aerial and a single dish, you are required to obtain permission for a second dish.
If you do not have permission, you can resolve the problem by having a quad LNB fitted to the bigger dish, assuming that is aimed at the Astra satellites parked in geostationary orbit at 28.2 and 28.5 degrees East. That has four outputs so can feed two satellite PVRs at once. If you need morefeeds then an octal LNB would serve.
I concur with MikeB that you need a 'proper' aerial for your terrestrial reception. A good log-periodic is advised as that will cover all current and planned future channel usage. Never buy one that is too small, it is better to have a higher gain aerial and if that gives too much signal you can reduce it with an attenuator if needed

MikeP: thank you. I suspect need new equipment the only thing I wasn't sure is that when I click on the map showing freeview map it has green all around apart from some grey patches and I am in a grey patch so just thought it might be that before I buy something new. Thanks

Got a manhattan T1 box 35 that should do HD,.
It gets ch1 - 100 then does nothing up to ch 120. So all of th HD channels, it says Invalid channel number ??
What am I doing wrong?
TV is 720P capable, box is set to this, on HDMI lead and input,.
pe292lu high in loft, good coax 790 channels seen

steve: I've got the older version of one of these boxes, and they are relatively sensitive (although they have the tendency to lock up every so often, at which point you need to pull the power and let it reboot), so I can figure why your not getting your HD channels, especially since your seemingly so close to Sandy Heath.
First thing is to check that its not your system, after a rescan and making sure its locked onto Sandy Heath. Try swapping out the aerial lead, and obviously check signal strength. If everything still looks OK but no HD, then ask if you can use your neighbours aerial for a minute - if you do a scan for channels and it picks up HD, its your aerial system (although you would probably have noticed that when looking at signal strength).
If nothing works, it sounds like the box is duff and take it back. My betting is that either something is really up the spout with your aerial system, and its just about hanging on, or, more likely, the box is shot.

Hello I have freesat from sky .
My signal is perfect in dry weahter.
But whenever it rains even light rain my hd channels break up.
However all SD channels are fine unless it's very heavy rain it has to be heavy to affect SD but only light to affect HD .
I know rain always affects satellite signals but why does it affect hd easier and every time it rains .
It doesn't go off air just keeps breaking up every few seconds . Especially itv hd .
I've tried a few different boxes all the same .
My signal levels are 78% signal 90% quality .
I have a sky mini dish fitted with 1 wire to my sky box .
The faces a sky with no trees in the way but does face near a wall but the wall is quite few feet off .

Dylan:
Your problem is the mini-dish, the ones fitted by Sky are often too small for reliable reception when there is significant moisture in the air between your dish and the satellite. You cannot amplify the satellite signals so the only real solution is to have the dish replaced with a larger one and preferably moved away form facing the wall.
The one other thing you can do is to check that all the connections are making good contact and that the F-connectors do not have any strands of the outer metal braiding touching the inner central copper core.

Ok I see if that's the case though maybe the minidish should be abolished and people have bigger dishes fit by standard. Sky didn't install my minidish I paid for it 185 only last year .
I am so disappointed. But thanks for telling me the problem do you think in future they'll make a better dish by standard there's not much point in only been able to watch tv in good weahter most the time in good weahter you want to get out .
I've known other people have simlier problems with the mini dish I'm quite far south as well I'd hate to think how it would work in say Newcastle or blackpool.
At some point I'd like to get a dish that can get me channels from Germany and Europe as well as uk sat but at the moment finance isn't great so maybe then if then ill get a bigger dish . Is it possible to get a dish that will pick up all german and English channels and play them on the same box like a sky box or freesat box .
