Mr Peirce: Good evening, Mr Peirce. I apologise for not spotting your comments made on this site more than a week ago. You were correct to imply that your sister-in-law in Hordle, Lymington, would also be using the Rowridge transmitter as you do. If more than one viewer experiences problems with the same transmitter, then one of the affected viewers needs to report the problem. It may be reported to the company broadcasting the affected channel - i.e. the programme company or 'broadcaster', the BBC ( who have a department called 'The Radio & TV Investigation Service' (RTIS) or to the transmission company, Arqiva. Simple searches using a search engine online will give you contact details of any or all of these organisations, to whom a report of a transmitter fault can be made. Richard in Norwich.

I have recently moved and according to the postcode checker for SO32 2RR am receiving signals from Rowridge. However my loft aerial is pointing approx 45 degrees east of the expected direction. Neighbouring houses with external aerials all seem to be pointing in the "right" direction although with a mix of horizontal and vertical polarisation. My TV signal reception is good except on COM 7 although I can watch these HD channels through a Panasonic recorder. Before I start changing anything can anyone explain why this setup works as normally you only have to be a few degrees off to lose signal.

I want to expand the system with TV points in the bedrooms by adding a masthead amplifier/splitter to the existing aerial if possible. But I don't want to start until I'm clear on where the aerial should be pointing and whether I need to upgrade to an external setup.

Stuart Tier: Firstly, your loft aerial (which we assume you 'inherited' when you moved in) might just have been knocked, bodged, etc. By all means just point it towards Rowbridge (if you look at the DigitalUK site, you'll see the compass bearing in 191 degrees - having the postcode makes life much easier!).
The reason why it basically still works is that your just 28km from the transmitter, and Freeview is pretty forgiving. Obviously check signal strength (not too high, not too low), but moving it a little will hopefully get you that extra mux.

Since your only 28km away from the transmitter, and its apparently 45 degress off as well, wait until you've moved it to see what sort of signal strength/quality you'll get first, before worrying about a booster, etc. Frankly, the signal could be too powerful already, in which case you can stick a couple of extra points on with no worries, and still have to kill the signal a little.

If its too low, then perhaps you might need to get another aerial, but if its working fine, why worry? This site will tell you loads about loft aerials, how to split the signal, etc Loft and indoor aerial installations for TV, FM and DAB

Stuart Tier:

Further to that said by MikeB, rather than adding a masthead amplifier (which is a single in and single out device) you would do better to include a distribution amplifier mounted in the loft. You may need to include an attenuator if the resultant signal strength is too high, you do not want 100% - especially on the HD channels as that tends to cause signal breakup as there is too much of it.

A distribution unit takes several inputs, such as UHF TV and DAB radio if wanted (with a suitable aerial) and feeds the signals to the several outlets on the unit. Some have four such but other have eight or more. Use good quality cable and fit the plugs carefully to avoid the fine braiding causing a short circuit which would kill the signals.

Hello. I live in the Dorchester area (DT1 2BT) and for the past few weeks my freeview digital reception on SDN Ch 25, ARQA Ch 22 and ARQB Ch 28 has been very 'flaky'. BBC A type on CVh 24 and D3+D4 on Ch 27 are fine. My external antenna is pointing towards Rowbridge

I haven't checked my internal cabling as to my mind the variable poor reception according to Channel doesn't suggest an infrastructure problem, but I could be wrong!

Any suggestions

Many thanks

Charles

Charles Turner:

It is always wise to carefully check all your internal signal cabling as some types of cable fault can cause differential effects on different signal frequencies. So I would suggest a careful check would be a good idea.

Having said that you are at about the normal limit for Rowridge, according to the map at Freeview reception at DT1+ 2BT for your location. So if there are any potential difficulties they would show up on the weakest signals first. According to the listing at Coverage Checker - Detailed View for your location, ARQA on Ch22 is liable to be the most affected by any reception difficulties. Ch28 is also a potential problem as the HD transmissions are of lower power, so more susceptible. Ch25 is also potentially marginal.

So a good aerial system is essential, hence the checks are well worth doing (or having done by someone knowledgeable).

For a number of years I have been using CH61 for watching Sky in other rooms. The picture is no longer as clear as it was with banding and shaking. If I assume 4G interference, which channel do you recommend I change to in SO24 9?

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.
