Freeview reception at BS13 8LF
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 5G-at-700MHz services that may interfere with Freeview reception. For actual mobile device reception prediction (at 800-960MHz and 1710-2170MHz) see these phone operator's mapping sites: Three O2 EE VM

I live almost next door to a freeview light transmitter (Rosehearty transmitter) so much so that there is no difference in signal with or without the aerial. The transmitter that provides full coverage is the Rumster Forest Transmitter. If the light one is in the line of sight path of Rumster Forest will I still be able to get the signal from Rumster Forest?

Jonathan : Whether it's a transmitter or any other type of structure in the way makes no difference - the question remains: can you receive successfully from desired transmitter?

Jonathan : The answer to your question is totally dependant on whether or not the signals from the local Rosehearty stations 400 watt transmitters are strong to the extent that they are swamping your TV (or boxes) tuner whereby making it insensitive to picking up transmissions from another station located somewhat further away, the station in question being Rumster Forrest @ 64 miles / 314 degrees radiating on horizontal transmission, whereas Rosehearty radiates on vertical transmission.
Although a terrain check between your location and the Rumster transmitter only indicates the presence of a minor line-of-sight obstruction to the signal path of the signal from that station, but though, due the curvature of the terrain between the two positions I would think that if any reception was possible (which I doubt if it would be) reception would be totally erratic.
Freesat is really the only way of receiving the full range of channels in areas such as yours.
By the way, should at any time you wish to test if its possible to receive any transmissions from the Rumster Forrest transmitter, flip your aerial onto the horizontal mounting position, then turn it slightly backwards (anticlockwise) to point to roughly 314 degrees, then go into your devices tuning menu / manual tune and enter Rumstrers SDN / COM4 Mux on C30 into the box, this being ITV3 which is not on the Freeview light transmitter.

Mr T Meadows: A quick look at the Digital UK Coverage Checker tells the story and the terrain plot rather nails the likely cause!!
The PSB channels of Hemel Hempstead are co-channel with the COMs of Hannington, albeit opposite polarisations.
The terrain plot to Hemel Hempstead shows clear line-of-sight at 11.4 miles:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The plot to Hannington also shows clear line-of-sight at 43.1 miles:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The plot for Crystal Palace shows clear line-of-sight at 15.4 miles:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
Harrow Hill probably isn't sampled for this plot so that's why it's not shown as obstructing the path.

Hi Sutton Coldfield
I am experiencing poor subtitling on a few Freeview channels. The main culprits seem to be on your COM 4 MUX, eg Drama, ITV3, ITV3+1.
The problem I am getting is very poor synchronising of the subtitles. At times they are up to 10 seconds early, then they will stop, re-appear in synch and then gradually start appearing early again. On Monday evening I recorded George Gently on Ch 20(Drama) and Grantchester (ITV1). These two programmes overlapped between 8.00pm to 10.00pm. The George Gently subtitles were terrible whereas Grantchester's were perfect.
Have you any idea what may be causing this problem? I have had the problem for some time now.

Our aerial has been in the attic for 40+ years. During the summer, about 5 or 10 years ago, we were plagued with interference from France. In the last two or three years it has cleared itself up.
This year we are enduring interference, in the form of a mass of horizontal rectangles in the morning and evening. We have attributed all this to high and low atmospheric pressure (co-incides with the tides). Any suggestions for a non technician?

Hi Quentin
I would replace the aerial for a new one and replace all old co ax cables for double screened type same they use fort satellite tv cable. this should clear up your problems.. an aerial and cable 40+ years old do degrade over time..... causing interference and other problems

quentin: Have you as yet, verified if anyone else in your area is also suffering from the problem referred to with regards to a mass of horizontal rectangles afflicting reception in both mornings and evenings, something which comes into the category of being rather odd, as although anything of an alien RF nature clashing with a digital TV signal generally results in the break up of the picture, its not in the fashion of a clearly defined pattern such as you have mentioned.
On the subject of replacing the cable, although modern satellite grade cable is in most cases superior to coax made in the era you have referred to, but as far as killing off interference from France or any other European station is concerned, virtually nothing you (or anyone) can do will alleviate the problem, as viewers located in large swathes of the Southern areas of the UK can suffer from this at various times of the year due to reasons similar to what you have mentioned, although its usually at its worst during warmer weather.
