Hello - We live within about Half a Mile of the Sandy Heath Transmitter - I can see it out of the window looming over us all - & we have a couple of TVs with In Built Freeview. Is there anyone out there familar with the implications of the new 4G Service for those in close proximity to this Transmitter - in view of all the comments in the Press about Interference/Loss of Freeview Channel Access etc. & if this is likely to arise - & what is to be done in practice?

Bryan: The most likely scenario for problems from 4G signals is a weak Freeview signal being received in an area with a strong 4G signal. If the Freeview signal is then amplified with no steps being taken to reduce the level of the 4G signal the viewer will end up with a super strong 4G signal which is likely to overload the tuner. The problem is worse for viewers receiving C60 or C59 as filtering becomes more difficult. I don't know where the nearest 4G antenna will be in relation to your location, but as you are close to Sandy Heath, so unlikely to have any amplification and receiving frequencies away from those to be used for 4G you will probably have no problems to contend with.

Bryan: In addition to the response from KMJ,Derby, 4G signals will be vertically polarised. Your Sandy Heath aerial is horizontal so this is another factor which makes you even more less likely to be susceptible to problems with 4G interference.

Any suggestions please?
Switched room 1 to HD PVR & TV and now seeing break up on various channels. Have an amp inline in th aerial feed that serves these 2 boxes, and a second (SD) PVR in another room. Only other thing is that the old TV was not on aerial as it was analogue only. Could the extra device (or the cable In place) be an issue,
Am testing removing the aerial cable for PVR to TV to see what happens, we mostly time shift, so it's not a big deal.

PJB : Well its not really easy to advise on this without having knowledge of your location or at least one from nearby such as a shop, as the signal levels expected at your location cannot be assessed, but try a test with the aerial by-passing the in line amp and going either straight into the PVR or the TV, giving an update on results.
Although by being unable to assess the signal levels expected at wherever you might be located complicates the issue.

My Mum and Dad live in Langford and do not get channel 10, ITV3, or Quest channel 38. The ariel is a digital one and situated in the loft. Is the ariel in the loft to blame?

Peter: They should try a manual scan of UHF channel 51 if there is a manual tune function. Having entered the channel number, but before pressing the button to scan, wait and see what the strength and quality on that channel is, if it gives such readings.
On the basis that they are only 5 miles from the transmitter they wouldn't be expected to have an issue.
The main possible thing could be too high a signal level:
