Mike Sugar: The latest (1/8/2016) "Planned Engineering Works" notice board has Ridge Hill listed with the status of "Possible weak signal", this situation being of a somewhat regular occurrence.

Mike Sugar: Please ignore that said, as I posted this in error.

Moss: Yes, as Belmont's channels span from C22 - C60.

Although being unaware of the type of aerial you have in mind, I would not hesitate in using an aerial of the Log periodic variety such as seen in the undermentioned link, the Log36 having an element of built in protection against 4G transmissions, that is should you reside in an area where the possibility of interference from same exists.

Richard Cooper : As an engineer of many years standing I am already perfectly aware of the situation with regards to the re-classification of wideband aerials and for the reasons mentioned. However, that said in my reply to Moss applies irrespective of what type (W or T) he had in mind, as his posting (to me anyway) suggested it being one more of seeking confirmation to what had already been decided upon, hence no need to go into explanations re identification letters.

Rowridge (Isle Of Wight, England) transmitter
Thursday 11 August 2016 12:07AM

Nigel : Your location is indicated as being completely outwith the coverage area of Rowridges H polarised low powered LSO transmitter, hence the reason why the Multiplex transmitter channel (29) broadcasting this programme is not listed in DUK's reception predictor for your location, the fact of you having previously been able to view this channel being most likely down to favourable reception conditions appertaining to the last time you carried out an auto-tune, a situation which has now changed.

Rather than carrying out a series of auto-tunes in an attempt to recover the channel, go into your TV or boxes tuning menu and select "manual" tune followed by entering 29 into the box, then pausing at this point, i.e: do "not" press search or scan, as this procedure has the effect of making the tuner act like a form of signal meter devoid of reception threshold limits (which applies in auto-tune mode) likewise indicating the level of any signals being received nomatter how low they might be.



Further assistance as required.

Moss : Basically yes, although knowledge of your location would have been of assistance, as this would have enabled a check to be made on the signal levels etc expected at said location.

By the way, there's two versions of this aerial, the original UNIX 32 covering channels 21 - 68, whereas the UNIX 32T is the newer version designed with an element of protection against 4G transmissions, i.e: covering channels 21 - 60, although should you reside in an area with the potential to be affected by 4G transmissions? the standard UNIX used in conjunction with a 4G filter gives superior results over that of the later 32T version.

Further advice available as required.

Moss : No problem Moss, pleased to have been of assistance.

However, as far as your UNIX 32 aerial is concerned, this should be perfectly OK for use in the Skegness area, as one or two test codes indicated that the area has a clear line of sight with Belmont's mast, although if you do experience any problems, then a post code or one from somewhere nearby will be required, e.g: a shop incl Post office.

Moss : Well, up to a point anyway, that can be quite true!, but one gets what one pays for as far as construction (ruggedness) is concerned, even although the receptive qualities of some cheaper alternative products can be very similar to that of the more expensive equivalents.

However, the item advertised in the undermentioned link could well be of interest.

Nigel : Yes, high pressure certainly does have an affect on reception, and in most cases one of a dastardly nature, although occasionally (very) it can be positive by enabling a signal to be received from a transmitter normally just out of range.

I had a quick look at the pressure maps before making this reply, and judging by that seen it would appear that the UK is in for a rough time of it for the whole of next week as far as reception problems are concerned, as a series of waves of high pressure are seen to sweep across most of the UK excluding the Northern areas of Scotland, with the South Western area's being severely affected at times.

Needless to say, high pressure is the most likely reason for the problem mentioned.

Ryan Leask: In addition to that said by Richard Cooper. Should your parents indeed be using a Freesat box? then the problem referred to can be caused by a number of different reasons, these ranging from either the satellite dish having been moved (possibly blown) out of alignment, or a fault having developed on the LNB fitted on same, or even failure of the actual Freesat box itself.

However, more information is required in order to assess which of the aforementioned is most likely to apply, such as the model number of the Freesat box in question, and have your parents carried out a signal check on the box? this usually accessed via the set up menu.

Further advice dependant on reply.
