Roger Huxtable: Your location is indicated as being able (in theory) to receive about the same level of signal from either the Guildford transmitter (@ 6 miles / 316 degrees) with aerial mounted vertically or Midhurst (@ 13 miles / 218 degrees) with the aerial being mounted horizontally? would you know which of the two applies?

The way to check being to carry out a signal test on BBC1 and note the mux channel number shown along with the strength / quality indication, Guildford being Ch43 whereas Midhurst is Ch55.

However irrespective of which of the two you are receiving from its noticed that the signal path from both sources is being obstructed by reasonably dense trees, these not just being in the immediate vicinity but at various points along the way and which could well be responsible for your problems by intermittently blocking the signal, should this be the case then a so called higher gain aerial is very likely to make the situation worse by the fact that high gain aerials are only that because they effectively focus on the signal, but if this is being obstructed / scattered by being reflected from the trees then a wider pick up aerial such as a Log type used in conjunction with a high gain variable booster is more likely to improve the situation, albeit that it will never be perfect.

Further advice dependant on reply.

I used to get good digital signal but suddenly from last two-three days i completely lost digital TV and radio signals.

I am based in Guildford, York road. did any one facing this problem??

Sam: I'm about 25 miles south from you in a village called Thakeham. I lost everything sometime early Saturday AM. 3 TVs all have the same issues, so it's signal related. 2 of them will find channels, but my Toshiba can't find anything.

I've checked all that I can (cables, booster, connections in the loft, factory resets, turning my Wi-Fi off etc) but unable to check the roof aerial as I'm lacking a tall ladder. Probably have to get someone out to check things over.

Bl**dy annoying as the signal has been fine for years and the digital aerial I've got is not 2 years old yet!


Sunday 16 June 2013 10:49AM

Jason Wright: In addition to the checks you have already made you should eliminate the possibility of the booster having developed a fault by connecting the down lead from the aerial directly into one of the room feeds, in other words bypass the booster.

jb38: Hi. Thanks for the advice.

I did take the booster out of the equation yesterday, no difference, but have not tried connecting the download lead direct to a room feed. To be honest it's a connection in the loft that looks a bit 'pro' to me to be fiddled with.

My Mum who lives 7 miles away in Billinghurst has now lost all her channels too. Coincidence?


Sunday 16 June 2013 4:53PM

Jason Wright: Being unaware with regards to the method you used to take the booster out the equation as just switching it off would in most cases kill reception, if that's what you done? because apart from a faulty (corroded) connection where the coax terminates on the aerial then the only other reason for the problem has to be caused by the boosters internal power supply having failed (which of course they can do) or alternatively that the mains power supply to the booster has accidentally been switched off.

By the way Midhurst at just under 13 miles away is indicated as the station covering your area and nothing as yet has been posted on the engineering page as far as any problems are concerned, nor is any engineering work taking place at the station.

As far as the booster connections are concerned what you have said could indicate that its fitted with "F" connectors, if it is then you should unscrew the gland nut retainers on the two cables previously referred to, i.e: aerial in / TV feed out, then hold the two plug bodies together with a piece of Scotch tape or whatever and bridge the two copper wire centre connectors together with a piece bell wire or similar.

I realise that this is a bit of a bother as a back to back "F" coupler of the female variety should really be used, but this action "might" avoid you from having to call out an engineer with the costs that can involve, because should the booster prove as being defective its not exactly a high-tech operation to replace it.

Sunday 16 June 2013 7:57PM Pulborough

Thanks JV38. Booster has power and the LED is on, but I'll bridge the F connectors as a test.

Looks like a booster or aerial connection issue to me now. My Mum's channels have returned except Channel4 and 5.


Sunday 16 June 2013 8:35PM

Jason Wright: I will say that on most boosters the LED works off the same supply as the amplifier, but though on others it doesnt and can still be illuminated even although the amps not receiving any power, this being why its always a safer bet to try bypassing it first before calling anyone in.

Needless to say that if nothing is received after having carried out a retune with the aerial going directly to one of the TV feeds then this unfortunately points to a possible problem on the aerials termination box, and although a long shot, but if you had an old set top aerial around you could temporarily connect that into the boosters input socket rather than the main aerial and see if that resulted in anything been seen, this can sometimes even work (dependant on signal strength) using a short length of wire (5 feet or so) pushed into the middle of the "F" connectors socket.

Maybe you could also make a note of the model number printed on the splitter / booster and include that along with the result of your test.

So I bypassed the booster by just using a normal aerial patch lead in use on one of my other TVs. Retuned, but got nothing watchable. It finds channels (between 88 and 137 in total) and lists them from channel 800 onwards on my Sony. My Tosh can't find anything anymore. BBC 1 is blocky and pixelated with no sound and then then screen goes black with a no signal message.

As far as I remember the booster is a remote power one that boost the signal to a distro box in the loft. The box has 1 input and 4 outputs, with only 3 outputs in use. The installer said we needed the booster as the signal strength was poor in our area. The booster is a Labgear R08W18 3w.

The aerial cable run from the aerial to the distro box and then down to the main TV has has got to be about 12m, so I'd hope there was enough there to get something watchable?

Don't think there's much more I can try. I'll give the length of cable a shot, but not hopeful.


Monday 17 June 2013 7:43AM

Jason Wright: Unfortunately I was unable to check the specifications of that device as the number given is not recognised by Labgear, but though judging by what you have said if its a distribution box come power supply for a mast head amplifier then the test requested would not be valid as it requires to be made externally.

Needless to say that in this instance its best to have someone check the aerial out.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
