Dave Lndsay: we also have lost our signal BA21 3JH. Television working fine until 11 a.m. and then no signal and sometimes it will come on again later on in the day and and then go off again about 7. This has been happening over the last few days. We have bought another amplifier/booster and still no signal. Can you help.

Mrs Ila Shepherd: You should, according to DigitalUK, get a really good signal from Stockland Hill, and I'm frankly surprised at the need for a booster, although there is some high ground which might be a problem along the signal path.

However, if your getting 'no signal', then your TV is telling you thats its getting nowt (a booster will make no difference). And since there seems to be no prblem with the transmitter, the fault is within your system. If its regualrly going off and coming back on at regular times, thats probably 'single source interference' (you can google it on this site), which is most likely a dodgy timed thermostat, etc.

If its a bit more random, then its more likely to be a frayed/loose connection, water in a connection (a classic after heavy rain), etc. Check each bit of the system back towards the aerial, to make sure everything is OK, and obviously make sure that there is nothing that is coming on at those particular times which might cause interference.

Hello,

Living in Taunton, Somerset, we are only a short distance to the Devon border, yet get news for Bristol and even Wiltshire which is over 80 miles away!

how come our region doesn't work off the stockland hill transmitter? can I retune my freeview to pick this up?

Thanks

Matthew Jackson: The editorial regions of both BBC South West and ITV West Country (from Stockland Hill) don't cover Taunton.

ITV Media :: Why ITV

You are, of course, free to tune to any transmitter that's available to you. If you wish to tune to Stockland Hill, assuming it's available at your location, then you may require a different aerial and will certainly require it reorientating in order to give the best possible reception.

Her we go again Signal has been fine all winter and as soon as we get to May it becomes useless until about October . We get freview from both Stockland Hill and Mendip Transmitters The BBC signal has now droppped to below 50% and is very erratic and becomes unwatchable and unrecordable. I have a Freview HD TV and Freeview ordinary recorder and both are suffering the same. The HD channels are fine at 100% signal but standard BBC is below 50%. Something outside of my property has to be causing this new yearly event which started in 2014 and has returned again now things are warming up. There is something wrong with the transmissions in the Yeovil area. BA21 4PH

A Peapell: Which PSB1 multiplex (BBC standard definition TV) does this relate to (from which transmitter)?

If you have two aerials combined into one feed cable then you could potentially have had an issue with reception of PSB1 from Mendip from 27/03/13 onwards, depending on where your diplexer splits. The diplexer is the thing that combines the two feeds and for each aerial filters out channels that the other aerial doesn't filter.

If your diplexer splits at C51 then from the date above PSB1 and COM4 (ITV3 etc) from Mendip moved downwards to C49 and C48 respectively, meaning that you would then be using your Stockland Hill aerial to receive them which could account for variable reception.

Dave Lindsay:
Channel 22 and 26 are the problem ones I have had to get an HD recorder as can't record the standard channels as signal strength goes from zero to 80 all the time as well as quality and drops out or pixelates
Something else has to be interfering as canel 49 and 54 are OK from Mendip transmitter, all systems have been retuned but still doing it - 4G no doubt!!

A Peapell: Well then, if it's 4G interference, then at800 are the people to call:

Dave Lindsay:

I am only guessing I have no idea, and am looking for someone to tell me and my neighbours why we are getting rubish reception for the last 2 years as soon as the weateher warms up until it cools down again??!! Nothing else has changed in this period and it is several properties with this lack of reception. Tonight it was going from zero to 80 in stength/ quality within 15 seconds and up and down like a Yoyo all across BBC especially.

A Peapell: If interference from 4G signals is suspected then the course of action should be to call at800 as this will ascertain whether it could be the case or not. They will do a look-up based on postcode and give an immediate answer.

As the issue occurs during the warmer part of the year and it affects a number of properties then I would suggest it's likely to be caused by vegetation, for which there is nothing you can do, other than perhaps raising the height of your aerial.

Looking at Streetview, Folly Fields is on a slope and I can see trees in the way in the direction of Stockland Hill.

Now to look further afield. Here is a terrain plot from your location to the Stockland Hill transmitter:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


You may have clear line-of-sight at 23 miles. However, there are two peaks around 10 to 11 miles out which, although they don't obstruct line-of-sight, they are within the first Fresnel zone. The first Fresnel zone is shown on the plot and is between the straight yellow line and the purple one.

Anything which changes in the zone could potentially change the reception. Clicking a point on the plot takes one to a map indicating the point. These points are Warren Hill and St Rayn Hill, adjacent to the A30 as it runs between Crewkerne and Chard. There are trees on the former.


Signals travel in straight lines. When a signal passes through an object it gets diffracted, like how water diffracts light. Therefore if the object that is diffracting changes, the degree of diffraction may change. This could the cause of your difficulty.

Different frequencies travel differently as they are affected in different ways and to different degrees. The only way they would all travel exactly the same and therefore arrive at the receiving location exactly the same (all good or all iffy) is if there were absolutely nothing around, no objects, no ground and no air (a vacuum). As soon as you introduce these things you bring in variables whose effect varies by frequency.
