Freeview signal/aerial problem

Is there any equipment that i could buy to solve this, dont really want to fork out to have the main aerial from the roof adapted just for this.

Depending on signal strength in your area you may get away with an amplified indoor aerial from somewhere like argos (see this product) which you may get away with, failing that i'd suggest buying a loft mount aerila kit, and just drop the wire down from your loft into the bedroom.

Have you check the box on your downstairs TV (with a roof aerial) to check that you get a good picture there and it is not just that you live in an area with bad freeview/have a defective box?

go to bbc homepage,then into freeview,do a postcode search to confirm freeview is ok in your area.A strong analogue signal does not guarentee a strong digital one, therefore an indoor aerial is NOT recommended.ALSO an important point the actual channel numbers are slightly different and in some areas a totally different aerial 'group' is required.also the aerial is mounted horizontally or vertically, The group refers to the blocks of channels in the uhf tv band ie 21-37 is group A 37- 50 is group B, 48-66 is group C. etc,.... a booster is only good if the signal is reasonable, below a certain level it will be useless...hope that is of help

I DID THIS AND IT SAYS NOT AVAILABLE I HAVE LOOKED FOR AT LEAST A YEAR NOW AND STILL NOT AVAILABLE DOES ANYBODY WHO SAYS IT IS NOT AVAILABLE GONE FOR IT AND FOUND IT IS?

THANKS pAUL

So what did this website tell you about your predicted signal strength and suggested antenna then :question:

the following: by the way means nothing to me?

Notes
The results from this predictor should only be used as a rough indication as to which transmitters might be available at a specified location. Please note that the calculations take no account of local surroundings (e.g. trees and buildings), the directional radiation patterns of some transmitters ( e.g. coastal restrictions) nor sources of interference (e.g. strong adjacents). For points in Ireland, the effect of the intervening terrain (e.g. mountains and valleys) is also currently not included. Where the prediction shows a choice of transmitters giving similar field strengths, it is usually worth considering the closest first.

Please note that for combined analogue and digital reception the choice of a different aerial or even a different transmitter might be necessary: [Link to UK analogue TV reception predictor]

Transmitter information copyright BBC, Crown Castle UK, ITC, NTL and SDN 1998-2005. Public domain information only.

Key: Aerial groups: A 21-37 red, B 35-53 yellow, CD 48-68 green, E 35-68 brown, K 21-48 grey, W 21-68 black; Pol = polarisation (H horizontal, V vertical); ERP = effective radiated power; AOD = aerial height above Ordnance Survey datum; OD = site height above datum (metres); Bearing is from Grid North (Magnetic North is a few degrees West of Grid North - check local OS map for present variation and add it to Bearing for precise compass direction)

"Antenna suggestions" are a rough guide only; a minimum height of 10 metres is normally recommended. Where an "amplified extra hi-gain" system is suggested, the minimum would probably be a good multi-director Yagi array with a low-noise masthead amplifier.

Some postcode areas are rather large - better precision is possible using an Ordnance Survey grid reference, if available. Also, some postcodes have not yet been included in the database.

New: the transmitter OS grid references are now hyperlinked to our transmission path predictor. This is an experimental facility which might be liable to failure or other problems during its further development. In particular, the graphical output produced is currently Adobe PostScript ®, which might not be displayed correctly with certain browsers. To view the output with your browser, it will require a plug-in or helper application such as GhostView ® or Adobe Acrobat ® plus Distiller ®. Alternatively, the output can be saved as a PostScript (.PS) file for subsequent use. It is planned to make a different format available in the future.

A friend of mine needed to buy a signal booster to get a Freeview box to work. Once he bought it, everything worked fine. He bought a TV Aerial kit and dropped the cable down into the bedroom where the box was.
