Freeview reception at BT81 7TH
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.
You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.
You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.
These icons show the potential locations for 4G-at-700MHz services that may interfere with Freeview reception at some point from 2020 when the 5G 700MHz services start.

I live in Rhyl Ll18 4ED
Until around 11th Jan 2014 I had no issues.
During the following week, I noticed signal was varying but only on BBC Channels from Moel-y-Parc..
I get Service from Moel-y-Parc and I get Service from Winter Hill.
My Aerial is aimed at Winter Hill, but until now have had no problems picking up from Moel-y-Parc also.
The current problem with signal from Moel-y-Parc only affects BBC Channels, all the other channels from there are fine.
I have checked the various websites re any possible faults at Moel-y-Parc but they all say they are none.
Any ideas?

Mark Farmiloe: I think you need to look closer to home some sort of electrical interference. Even if the base station is 4G at 800MHz then it's quite a way away, plus your aerial is horizontal and its signals are vertically polarised.
If it starts and stops at the same time then that is likely to be some timed device. An AM radio (LW preferably) powered from batteries might be useful in tracking it down.
I have a Multi-band radio including LW, but no idea how to use it to track my problem down. Please could you enlighten me.

The TV is a Samsung UE46D6100SKXXU, the PVR a Panasonic dmr-pwt635.
Unfortunately I don't have access to the communal aerial to check for boosting - it was a fair guess on my part, but rather likely given the signal strength and that it is likely 30+ years old.
What is odd for me is the hd channels were working fine in August - the TV was still tuned to them, but displayed "no signal" and disappeared when I retuned. The PVR was 2nd hand from Bedford and also had them still tuned, and half a mile down the road at my parents it also can find them.

Dsb: Being on a communal aerial system somewhat ties your hands as far what you can actually do is concerned as the level of the signal received has been adjusted by the engineer who installed the distribution amplifier.
However you should still carry out a signal check to see if anything is being received (no matter how low) but by using the Panasonic 635's tuner for testing purposes rather than the TV's, the former being more user friendly as far as "manual tuning" is concerned.
The procedure used being to go into the tuning menu and select "manual tune" then enter C21 into the box (Sandy's HD mux) but do NOT press OK to start the scan, because if anything is being received its level will appear on the strength / quality indicator bar, if though nothing is indicated then press OK just in case the box isnt capable of being used as a signal meter.
By the way if the menu only allows the frequency to be entered rather than channel then C231 is 474.2 Mhz, and if the decimal point is not accepted then 474.00 is quite OK.

Dsb : Re very last paragraph, the channel referred to is of course C21 and not the typo error of C231.

`Recently purchased a Bush Freeview HD box. Non HD reception and quality very good on all channels - on screen signal info indicated 98% quality and 90 - 100% strength.
HD via channel 32, BBC News, BBC 4 etc, show 5% quality and 100% strength, but no problems.
HD via channel 21, BBC1, BBC2, ITV1 etc, show also 5% quality and 100% strength, but suffer from intermittent picture and sound break up.
We are located 28 miles from Sandy Heath and have a wide band aerial. Any suggestions as to the cause of the problem would be most appreciated.

It appears that having 100% signal, especially on HD channels is not a good thing at all and causes the problems you report.
YThere is a section of this website dealing with having too much p0f a good thing and makes several good suggestions that have helped many people.

Hi all, I live in Coventry just of the main A45 road, I have watched freeview successfully for a long time. I have received one of the postcards ref the 4G interference and sure enough I cant get the majority of the freeview channels. What puzzles me is that I can still receive channels 3,4 and 5 and some of the more obscure channels, but not all of them. We have tried re-tuning to no avail. My question is, that, logically, if 4G is the cause, why can I receive certain channels but not all of them, as, surely if 4G is the cause, it should block out all channels and not be selective. I believe I receive from the Leamington transmitter, would redirecting the aerial to Litchfield help, do you think, I'm 74 years old so any help which does not cost money would be appreciated. Thankyou.

Glenys Sephton: Absolutely not as different frequencies are affected in different ways.
Have you fitted the filter behind the TV set?
If you have a booster then the filter should go before the booster.
