Malcolm Ward: No, you cannot convert signals from a satellite into ones that a "Freeview" receiver can work with.

You will need to either:

1. Purchase satellite receivers (e.g. "Freesat") for all rooms served by the dish, or;

2. Install a terrestrial aerial.


It is likely that for each wall outlet, there is a cable (or perhaps two cables) from the dish to the outlet. You could therefore use the existing cabling for terrestrial services. To do this you would need to remove the cables from the satellite dish. Then install a terrestrial aerial which goes to a splitter (either powered or non-powered). Each output of the splitter would then connect to each cable you've removed from the dish. At each aerial point replace the threaded F-connectors with coax ones. This would save you having to re-cable.

The only thing to be wary of is that not all areas can receive all Freeview channels. If you are in an area served only by limited channels, then you may decide to go down the satellite route.

If you give your location, preferably in the form of post code (or perhaps nearby post code) then an assessment can be made as to the likelihood of reception of all Freeview channels.

Malcolm Ward: I should point out that if you are in an area served by Mendip, then you will be likely to be able to receive all Freeview channels.

How strange, I live on the fringe of the reception area (according to the map) and have had excellent reception all week. Could it be that Alison Armshaw is getting a signal which is too strong since the power was upped?

Like many others, we have a pretty much non-existent service at the moment. The main TV set downstairs (Toshiba) uses its own Freeview decoder, as well as a second F.V. box (Sony) which feeds an old PVR. We have a second set upstairs with a second rooftop aerial point connected to a Humax Freeview decoder. The boxes downstairs are the ones with the problems (no signal) but strangely, the Humax is fine. But connecting the aerial directly to the Panasonic F.V. system upstairs gives the same problem as the set downstairs - no signal.

All this started a week or so ago, with frequent "If you lose Freeview channels after X date, you may need to retune" messages on all systems, which seems to have coincided with analogue switch-off in London. I have been looking around at pages and threads on this site, very interesting stuff.

We have not had these kinds of problems before and nothing else has changed; I have retuned all the Freeview boxes to no avail. I am now thinking it may be a physical problem with the aerial. Any ideas? The aerial is on the roof.

Thank you.

Ben Ward: Chances are that you now have too much signal. Along with the retune last Wednesday, two of the multiplexes quadrupled in power. Too much signal causes the signal to be distorted when it's amplified, either by external amplifiers/boosters or by the gain control or mixer circuits within the box or TV. Error correction can handle a certain amount of distortion, but too much of it and there are too many errors to be corrected.

Different boxes can handle different amounts of signal before distorting it too much to be decodable, and different boxes have different levels of sensitivity to quiet signals.

I'd start by removing any amplifiers, and if that doesn't sort it, add some attenuators to bring the levels down.

Digital UK predict 100% of locations in your grid square should have at least 99%-reliable signals. This is usually a good indicator that signal levels could be too high.

Ben Ward: Check that the receivers are tuned to the channels used by Mendip and not Bath.

You should only need to check BBC One, ITV1, BBC One HD (if applicable), ITV3, Pick TV and Yesterday. The UHF channel numbers are at the top of this page.

Mike Dimmick: For some reason the DUK Tradeview predictor suggests four digital transmitters at Ben's location, but only gives a reception prediction for Mendip.

I really appreciate the responses, guys. The 'too much signal' idea is very interesting; I moved my only working decoder (the Humax) to downstairs, and connected it up there. Of course, it works fine which kind of confirms that the Humax is the only decoder of my four which can handle a possibly too-high signal (Mike's point).

Dave, I will check my local channel tunings. I'll post back with my findings.

Regards,
Ben

Hello, following the recent upgrade to the Mendip transmitter I've lost a number of channels (down to 92), while my parents who live 1/2 mile down the road are up to 140. I can see the transmitter from my property so definitely within range! The arial is shared with other properties. Can you tell me if something needs to be done to the arial to get the other channels? Thanks!

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
