Freeview reception at CF31 2LX


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.

Jeff Sutcliffe: In situations such as yours where you don't have line-of-sight, you are relying on refraction. Consequently, in some spots one signal may be good and another not so. It is always possible that C50 (the BBC channel) isn't good where your aerial is, it never having been used before.

Hi, i am interested in 4G signals (at 800MHz). If a transmitter is transmitting channels say at (uhf) channel 30 (which is no where near 800MHz) what factors would lead 4G to cause problems in this situation?
Thanks

Ross Taylor: The problem that 4G can in certain circumstances cause is only one of its transmitter creating a powerful RF signal that's capable of swamping the wideband input of a TV or boxes tuner thereby desensitizing it to receiving TV signals.

Although having expressed my view in the past insomuch that I think the whole issue is being somewhat hyped up, as any powerful RF source that transmits on a frequency near to (not actually on) that used for TV reception is equally capable of desensitizing the RF input circuitry in a tuner, as it causes the tuners AGC (automatic gain circuit) to cut back the sensitivity of the tuner, this in turn also kills the TV signal.

The point to remember being, that any wideband tuner such as used in TV's is always susceptible to sensing RF signals near to its operating range, the tuner doesn't actually require to tuned to the offending signal, and as far as Ch30 is concerned, in my opinion any TV receiving programmes on mux Ch30 is only ever likely to be affected if the 4G transmitter was located at less than 30 metres or so away and was working at maximum power, AND that being coupled to the tuner fitted in the TV or box being one of the more mediocre types usually found in lower end devices.

Hi

I have "lost" Yesterday TV following a re-tune of my TV and Hard Disk recorder (twin tuners). All other stations are returned as they were except for this one. On a secondary TV with a Digi-box Yesterday is still received with no problems. I dare not re-tune for fear of also losing from this arrangement.

Any assistance on how to recover this station would be most gratefully received

Thank you
David

David : If you are receiving from Bluebell Hill then go to the manual tune function and scan UHF channel 54.

Thanks Dave, We have tried an AM radio but can not find the source to our interference. The times that this happens is 7.20AM-10AM then again at 4.20PM-10.20PM then the picture is perfect again. I've heard about the testing of 4G services, could this be the case if so how do I check? Any Ideas? Thanks Becky. (52.2724,-0.8316)
