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?

We have recently moved from PO31 7DQ to PO31 8QY. Our signal was great at the previous address but since moving 4 days ago, we barely have any channels (it says it's tuned 33) but there is either no TV picture or sound on the screen, or it's jittery and crackling. Any ideas of how to move forward with this? Presumably other people in the street watch the TV?

Looking at the mapping and transmitter recommendations, you are in a spot that can have difficulties due to the terrain (hills, etc) and possibly buildings. The transmitters available are Rowridge and Hannington (west of Basingstoke).

Have a look to see which direction your aerial is pointing. If it is about due North, then it is looking at Hannington. If it is pointing roughly south west then it is looking at Rowridge. Which transmitter were you using at the previous address? It may be that the aerial at the formner address is aimed at a different transmitter, so it may be worth doing a full retune.

There may also be some issues with 4G signals. If you look at the mapping on Freeview reception at PO31+ 7DQ and zoom in to your home area you will see that there are several mobile masts close by, some may be carrying 4G services. It may be worth contacting at800, their contact details are at If it is likely that you are being affected by 4G signals, they will send you a free filter to fit into your aerial lead.

Let us know if any of that helps.

Jemma: check that there is an aerial connected to the lead feeding the aerial socket on the wall, if this is the arrangement in your home. Sometimes the cable end is found to be coiled up in the loft! A cable connected to a satellite dish will not be suitable for freeview reception (applies if a former occupant used a sky box to supply their tv channels). Another thing to check is that the tv tuner is not storing channels from Rowridge, having found them first in the scan, when the aerial is pointing to Hannington. A look at google streetview suggests that many aerials in the area are pointing to Hannington.

I have no Arial issues but over the last 4 days BBC 1 HD losses its sound the picture is perfect. All other HD channels are fine including BBC 1 none HD. I have returned my TV to the Rowridge Transmitter but the problem still exists. 18th March 2016.

KEITH HOBBS - Please see below and what type of TV do you have It's a BBC Transmission issue.

The mysterious sound problem silencing Freeview HD
WEDNESDAY, MARCH 30, 2016 A516
UPDATED | An increasing number of Freeview users are complaining about sound problems on the platform's HD service.
What started off as a trickle of complaints around the middle of March, the trouble, which affects viewers trying to watch some of the UK's most popular channels including BBC One HD and ITV HD, has now generated a number of threads on internet forums (here and here).
The sound problems appear to be mostly affecting certain Samsung branded HD TVs sold in recent years, which can result in viewers losing the sound until they switch over to a standard definition channel and switch back again.
It's only apparent on services broadcast by the BBC on Freeview HD, including BBC One HD and BBC Two HD as well as ITV HD and Channel 4 HD, which are broadcast on BBC capacity. BBC Four HD and BBC News HD are not affected by the fault; these channels are broadcast on commercial capacity.
Some users have been claiming on internet forums that they have been told by staff at the Freeview Advice Line that the problems could be caused by 4G mobile interference, despite the fault bearing none of the main hallmarks of 4G interference, and occurring all over the UK, regardless of the local Freeview transmission frequencies, which have a bearing on potential 4G interference.
What next?
Although there's no indication of a fix any time soon, since this article was first published, the BBC has issued a statement confirming it is aware of the problem and "working with manufacturers to identify the problem".
Reception problems can be reported to the BBC Reception Advice line on 03700 100 123 or Digital UK/Freeview on 03456 50 50 50. Samsung customer service is available on 0330 726 7864.


We believe we have identified the problem which is causing sound issues on certain televisions,when tuned into services on the BBC's HD multiplex. While we believe our broadcasts are compliant with the relevant international specifications, we think we can make some changes that will help the affected televisions.
The change will need testing before a roll-out can begin and we will update this page when we have more details.
We continue to work closely with the device manufacturers on the underlying problem.
Thank you for bearing with us and we are sorry for any inconvenience

@brian jones
I bet it's just because these channels have the highest bit rates and some TVs can only just cope.
One of our Freeview SD TVs at home sometimes becomes unresponsive to the remote for a few seconds on the highest bitrate SD channels (BBC mainly).

Brian Gregory: I'm no expert but surely, if it was a problem with 'bitrate' the picture would be the first to suffer?

Bit rate is a red herring! It is not relevant to the issues being reported/discussed.

I had assumed that aerials to receive from the Rowridge transmitter would be the conventional type with the dipoles(?) horizontal.

Someone told me that that was true until recently, but now the aerials should be mounted vertically, as the vertical transmission was ten times stronger. (I assume by 'vertically' they mean that the length of the aerial remains horizontal, but is rotated 90 degrees).

I cannot make head nor tail of the Rowridge data. I don't understand MUxs, channels, or Groups. All the aerials I see around here point to Rowridge and are mounted conventionally.

I am wondering if someone who understands these things can shed some light on it for me please, and confirm this?

Thanks (East Wittering)

Paul Curtis : Rowridges PSB1 - 2 - 3 multiplex transmitters have an ERP of 200Kw on both horizontal and vertical polarities but not where COM4 - 5 - 6 is involved, as 200Kw only applies to transmissions on vertical polarity, horizontal being limited to 50Kw to avoid the possibility of causing interference to Stockland Hill's COM transmissions on the same frequency, i.e: C25 - C22 - C28.

Many viewers located at the extremities of Rowridges coverage area sometimes experience slightly erratic reception of the three COM channels, likewise choose to use vertical polarity for reception to take advantage of the higher powered signal, the downside of this being, that this action restricts reception of Rowridges newer COM7 / 8 Mux transmitters, as these only radiate on horizontal polarity at a much lower power of 24.4 Kw / 25Kw respectively.

As far as your location is concerned, vertical polarity is indicated as providing a superior signal over that of horizontal on COM 4 -5 - 6, reception indicated on DUK's predictor as being variable on horizontal polarity.

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.
