The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Rowridge (Isle Of Wight, England) mast?

Nick Taylor: As Channel 5 is on the same Mux (D3&4) as ITV1 / Channel 4 etc then there is no reason for you not being able to view it unless some glitch has taken place in the tuner, therefore as a first measure I would try removing the the aerial from the device followed by carrying out an auto-tune for the purpose of blanking out anything stored in the tuner, once completed reconnect the aerial and make sure that you get a "no signal" message if you try to select a programme channel, if not (which is correct) then carry out another auto-tune to load the programmes back into the tuners memory.

If Channel 5 has returned good and well, but if not then you will have to carry out a factory reset on the hard drive device, this also brand dependant known as "default setting" or "first time installation".

I also meant to add to my reply, that channel 5+1 which you report as being able to see is not transmitted by the same D3&4 Mux as used by Channel 5, but by the COM4/SDN Mux as used by ITV3 / Drama / QVC etc.

Hi, I have full uninterrupted sight of Rowridge, but experience regular freezing/pixelating of pictures, this with a stated 100% quality but only approx 40% strength of signal.

I have an external HP aerial & am I postcode SO317 BB. What can you suggest please to ensure better reception & access to all published channels? Thanks.

Phil Clifford: If you put your postcode into this site (or just Digital Uk's site), you'll see that your just 23km from the transmitter, so its not surprising that your tuner is screaming - the signal is way too high.

I get digital TV transmissions from the Fenham transmitter. Do you know if there is information somewhere that will tell me when COM7 will be available from that transmitter?

Could one of our aerial installer friends advise me on a couple of points please.

A) I've had a leaflet through the the door today about 4G starting in my area (from you know who) but I was always under the impression that the Rowridge transmitter was immune from 4G transmissions because its channels are well away from the spectrum used by 4G. Am I a bit naive in thinking this and any idea how close you have to be to a 4G mast to expect any problems?

B) I had to have a new aerial/cable installation done a month ago come this Friday due to water ingression and everything has been fine until this past week when I've started noticing what I would call a 'shadow' effect (not proper ghosting) to the right of word banners (for instance rolling film credits are a good example) and people if there is a crowd on the screen (I've noticed it in particular when watching football as the players look to have little shadows chasing them.) I can't believe the new aerial is at fault here and wondered what causes this effect (Googling hasn't made me any the wiser.) Can anyone help me isolate and fix this effect please?

hi, I am a local RDI approved aerial installer

in response to A - you are correct in saying Rowridge transmits at lower levels away from 4G, however there may be parts of your system that are prone to receiving 4G such as a wideband aerial receiving 21-68 (which you shouldn't have as its new) and also an amplifier receiving 21-68, which again you shouldn't have, if you have an amplifier it should either be 4G protected but if you do have an older one which can receive 21-68 then your recent installer should have fitted a 4G filter in preparation for protection.

in response to B - from your description this sounds like an issue with the tv set itself

colin1951uk: In addition to jamie's reply, in areas where DTT reception is liable to be affected by 4G transmissions the reason for is simply down to the powerful (usually) RF signal transmitted by the latter swamping the TV's (or boxes) tuners input circuitry thereby desensitising it to the reception of DTT signals.

As 4G transmissions take place above C60 then the tuner swamping effect of diminishes in a downwards pattern from that channel, and as Rowridges channel span ranges from C21 - C31 then its highly unlikely to be affected "unless" the 4G transmitter is located within say 750ft or so of the receiving aerial, or at a slightly greater distance if its located directly in line with the signal path from the Rowridge transmitter.

Of course the other factor which does play a role in whether or not reception is affected by 4G is the strength of the signal being received from the Rowridge transmitters, because if the signal is inclined to be a little on the low side then the effect of 4G will be much greater, likewise less on strong signals.

I would advise you to leave things as they are for the time being as the 4G issue is somewhat over hyped, likewise you may find that your reception has not really changed after the 4G transmitter comes into service, however it would be prudent to try and find out where the 4G transmitter is located relative to that of your location.

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.
