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?

Get signal from Rowridge. Aerial is in loft. No problems with Freeview reception before the first retune. Since then many problems with picture/sound freezing, pixelation, etc. Had an 'aerial man' in. He said problem was low signal strength so fitted an amplifier and renewed the coax down from the loft to the set (its on the outside of the house). No improvement! Despite having a replacement amp with more 'boost' today we've still got the problems. Humax recorder shows around 76% on the signal strength with signal quality normally 100% but jumping around wildly when there's a problem

By the way its the coax that's on the outside of the house not my Freeview box! :-)

Phil Alcock,Southampton.You may have too much signal.Also loft aerials generally perform poorly than external mounted aerials.Check your loft aerial too if it is either polarised horizontally or vertically and also if the tip of the aerial is coloured red which denotes a group A aerial or the tip is coloured black,denoting a group W wideband aerial.

Mrs Thomas: If you do a firts time installation on the TV, at the end it will ask you to select your country, Primary and secondary region, if you set these to UK or GBR for the country, England for Primary region and where ever you are at present for the secondary region, the 3rd region should be left blank, you should get all the channels back, I am a TV technician for Argos and if you call 08456040105 and ask to speak to Fraser I can talk you through this over the phone.

I have lost all but about 6 channels despite retuning lots of times. I have no facility for manual retune and the above instructions are incomprehensible to me. I live in a small complex and I believe the aerial is on the roof of a tall building. I should be very grateful if you would tell me what I need to do whether it is a new box, new aerial or other. I have been told sevePleaseral different things including the fact that the reception from the transmitter is unlikely to improve.Please help. Julia Behn

Phil Alcock - I concur with Mark Fletcher. All you need to do is flip the aerial 90 degrees to vertical alignment (see my earlier post on 30 April - diagram here: http://bit.ly/IKM4PE ). This worked for my loft aerial and ancient cabling. 3 of the 6 multiplexes only broadcast at only 25% power on horizontal alignment, but full power on vertical. I usually get 90-100% strength, and no less than 80% on bad days (always 100% quality). So far no freezing or lost channels since I flipped to vertical.

Julia Behn - I'd call the management company (if there is one) and get them to send someone round to sort out the communal aerial. I did this a few years ago when I lived in a flat. The costs gets split equally between all leaseholders! Also, make sure they put the aerial on vertical alignment if pointing at Rowridge.

Despite clearing my channels both on my Freeview box & also on my digital tv & retuning both sets either I find I am missing channels or they pixelate or once found the channels are lost. Sky News, Channel 5, E4, E4+1, 5* & 5USA are the most ellusive.
My tv aerial points south to Rowridge.
What can I do to receive all channels, retain them & overcome the pixelation?

Shirl,Southampton.Switching the polarity of your aerial from horizontal to vertical is a start as the SDN,ArqA and ArqB commercial multiplexes from Rowridge only transmit 50kw in horizontal mode but 200kw in vertical mode.The reason for this dual polarity is that the SDN,ArqA and ArqB multiplexes from Rowridge on frequencies 25,22 and 28 respectively clash exactly with the 200kw horizontally powered commercial SDN,ArqA and ArqB multiplexes from Crystal Palace transmitter also on frequencies 25,22 and 28 respectively there.Hence the horizontally polarised 50kw SDN,ArqA and ArqB muxs from Rowridge are overpowered by the 200kw horizontally polarised SDN,ArqA and ArqB muxs from Crystal Palace and instead a 200kw vertically polarised equivalent to offset this problem on Rowridge was implemented and alleviates this difficulty as such !

Seem to have fixed the problem. Read that rotating my aerial from horizontal polarisation to vertical could do the trick. Since its easy as its in the loft (and no cost!) I tried it yesterday. Last night was the first time since the first retune for Rowridge that WE HAD NO PROBLEMS!
