Thanks Mark. I will do as you suggest. Could the drop out of nearly all channels be accounted for by this? If not who do we contact to try to get help? Are we just in a bad spot? If so who carries the can for downdrading our TV experience?

Any help appreciated.

Malcolm Butler.Im not a fully qualified professional i may add,im just an amateur with some knowledge of most things but i will endeavour to answer the questions you delivered to me in your last text.
It could be one possibility in the first question you raised about the dropout of all channels after 9pm onwards but ok the next morning during clear skies,if your aerial facing Rowridge from your abode which crosses the sea over Poole Bay/English Channel due to local atmospherics or inversion effect could be disturbing your reception during the late night/early hours period,or whether your aerial is black tipped a group W wideband aerial which performs poorly on a all group A mast like Rowridge in a poor/marginal area.
Your second question is a tricky one but you could try Ofcom.
Your third question is are there any obstacles from aerial to mast such as trees,buildings,etc,do you live on high or low ground or in between.
Your fourth and last question probably falls at the hands of any UK/worldwide governments as they orchestrated the switching off of analogue TV and the switch on of all digital TV,this process is happening worldwide,and there's analogue radio coming up due for total switch off in tens or twenty years time.
If you provide your full postcode preferably this is to ascertain reception likelyhoods in your locality,then myself and others more so the true pros on here will equip you with more fuller advice and assistance to you as such.

Malcolm Butler: Regarding the problem of your channels dropping out, much as I do not wish to appear as a prophet of doom but as an engineer I have to say that there is very little you (or anyone) can do about that type of situation "if" its affecting all or most channels, as this indicates that its not co-channel interference being caused by atmospheric conditions but one where the only reason you are getting a signal in the first place is because the signal is being channel along by the reflective actions of the clouds, hence as you have obviously observed that when the said cloud cover vanishes so does your signal.

I have been involved in the past with trouble shooting missions to some of the more remote areas where this type of problem is common place, and although as aforementioned there is very little anyone can do as far as resolving the issue is concerned, such as spending time trying the aerial in different positions etc which in most cases is a totally futile operation, albeit of course this procedure "is" very effective on many occasions with other types of reception problems, however in your particular type of situation there is one thing that sometimes does help and it involves the use of a 20db variable gain booster such as obtainable from Argos, item
number: 534 / 4235 (£11.99) a link for same below.

Of course the use of this type of device only really helps in situations where when the signal drops out its only because that it has dropped to a lower level and "not" completely vanished altogether, something which unfortunately can happen, but the procedure is to check the signal strength / quality whilst reception is basically OK and making a note of the indications seen then when the signal drops out make another similar signal check, as in most cases even although the picture may have vanished the signal will still be there but just at a level that's under the reception threshold of your receivers tuner, once again making a note of the indications seen.

If the test made when the signal drops out reveals that its still there but is only indicating around 20 - 30% or so and that the quality is not fluctuating to any great extent, then the addition of the booster referred to could well lift it to a level that's just high enough above the reception threshold to produce a reasonable (but not perfect) picture.

Another point to note with your type of problem is to refrain from using any type of high gain aerial, as the highly directional properties of this type of aerial can be detrimental to reception rather than assist it.

david cusworth: There are a number of possible reasons why you have no signal on C22. I am assuming that you have a signal from Rowridge on C25 for ITV3 & QVC, also C28 for Film4. If so, it is possible that the aerial is positioned where there is no signal on C22, or where there is sufficient pick up of the signal from Crystal Palace on C22 to block reception of the Rowridge signal.If the aerial is mounted for horizontal polarisation it is more likely to pick up interference from Crystal Palace , which is also horizontally polarised. Improved reception is available in many parts of the Rowridge service area by using an aerial (preferably one for group 'A') set for vertical polarisation, as the COM muxes are transmitted at 200kW vertical and 50kW horizontal. Check that there is no analogue interference on C22 from the RF modulator of a VCR or Sky box set around C22, also check by using a different brand of box that the problem is not caused by the inability of your receiver to receive signals with a frequency offset, as Rowridge actually transmits ArqA on C22+. The Digital UK reception predictor suggests that you should have good reception from Whitehawk Hill, although this too could in certain circumstances be affected by interference, this time from Midhurst, which shares C56 with Whitehawk.

Has anyone experienced a common fault with the HD channels on a


After about an hour there is break up of the HD channels only. I can then change channel, go back to the HD channel and reception is fine again for a lengthy period of time

If this is common to this model I will get a different brand.

Just wanted to see if there is a duff batch on the loose. :)

I am only interested in reviews on the box. There are no issues with the reception, as an installer the aerial is on

Over the last 6 months my aerial engineer has identified that we are suffering from an continual underlying analogue interference apparent across all muxes. At certain times this results in visual break up and interference across all my freeview devices in the house on all muxes apart from HD,( and across the Midhurst transmission as well as Rowridge VP.)

This interference is preventing us from siting the aerial in the most effective position and therefore making the whole system even further prone to weak signal etc.

Geographically we are in an awkward position anyway in so much that, although we are only 3 miles from the Midhurst transmitter but because of the topography we are forced to point the aerial at Rowridge VP.

We are in Kingsley Green, situated between Haslemere and Midhurst.

All cabling in the house has been replaced to a high standard and the interference is definitely nothing to do with internal house appliances/c.heating/wiring etc.

Stringent investigation by my engineer shows that the amount of interference increases markedly as the aerial is raised to the apex of the roof. At present we have sited it on the south side of the gable in order to shield it from these incoming signals which appear to emanate from the north. This does make a marked difference but is not preventing the interference altogether.

I understand that analogue interference which affects the BBC muxes, deliberate or unintentional is a reportable offence. I intend to report this situation through the BBC website. Can anybody enlighten me as to any other avenues I can take? And......has anybody in the area have the same problem?

hi, as your existing engineer has tried rowridge and midhurst i am assuming he has used the same aerial each time?

if so, then the aerial being used must be wideband which is not suitable for use on rowridge, a wideband aerial can receive reception from the whole spectrum 21-68 where a ***group a*** aerial should be used on rowridge, 2 benefits to using a group a aerial are 1-you only receive the reception you should be receiving and 2-the aerial is more directed to the reception your looking to receive.

a wideband aerial can receive signal from transmitters even if you are not pointing at them.

you are a very long way from rowridge to be using that transmitter so you need it to work as best as it can which means fitting a ***group a*** aerial.

is you aerial engineer from a reputable company?? or a diy friend??

with aerial reception each location is different, you could be having issues that even you neighbour doesnt have!!....

the thing with reception is sometimes simply moving an aerial a few feet to a different part of the building can make all the difference, location of the aerial is key to it working properly, sometimes it can be a matter of trying all parts of the building before fitting in the best location.

you must first be using the correct aerial for the transmitter you are using.

keep me updated on your progress.

Jamie...thanks for your reply. In response the problem I have is nothing to do with signal strengths or is analogue interference. It is apparent using either a wideband or a group A aerial and has nothing to do with which transmitter its pointed at whether Hannington, Rowridge, Midhurst or even Crystal Palace. Whatever aerial or whatever transmitter the interference is there. My engineer is a fully qualified reputable installer and is absolutely meticulous. This must be locally generated analogue noise and I have reported that through the BBC website. Thanks for your advice though and I will keep you posted.

Thats a difficult problem.

Not even knowing where the analogue interference is coming from.

Depending how many tv's you have on your system FREESAT could be a simpler system to connect to, it would be free from the interference you experiencing on your tv aerial.
