Freeview reception at CO7 7JS


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.

Is there a problem with the Freeview transmitter. I can receive BBC1 via Freeview but no other channels.

Sandra Church: There are no reported faults on the Crystal Palace transmitter. Given that it covers most of London, there would be hundreds of people complaining if there was, so start by checking all the cables and connectors behind your TV looking for anything that has become loose or damaged.

MikeB: Perhaps you should also mention the possible problem using simple signal splitters; most are simply a simple soldered junction o three TV type sockets which result in impedance mismatching and consequent signal loss. Even the better designed ones of hybrid transformer configuration need to be treated with care and each "output" port terminated (eg, connected to a TV). In either case, if not terminated it is possible that "stub effect" comes into play if/when an "output" TV lead is a quarter wavelength long (or odd multiple thereof) it acts as a short circuit. Obviously this extreme effect will not affect all channels but it may explain why some channels appear to be received OK and others don't.

I hope I haven't "overegged the pudding" or am "teaching granny to suck eggs". Whatever, it's sometimes better to look more deeply into alleged aerial problems than simply blame loose connections, etc.

response for jb38-
The combo receiver is labelled as "HD DVB-T2&S2 COMBO", sold by eBay site 'ukdigital15'. However, they are now selling a differently labelled combo.

GeordieLad:

Any passive aerial splitter will contain 3 resistors of 37 Ohms configured in a 'star' formation, one leg being the input and the others the outputs. I know of no splitter that is as basic as you describe. The main issue with passive splitters is the impedance mismatch you mention and the standing wave problems if the cabels are an unfortunate length. Plus the degree of signal loss with any such passive arrangement.

An active splitter would normall isolate each output so leaving one or more unterminated by a TV would not be a problem.

GeordieLad: Or you could start off with the most likely problem - which is that the lead has come out of the back of the TV, or that there is a fault between the split and tthat TV.

Hello, I live in Corstorphine, Edinburgh and get my signal from Black Hill...
I am getting terrible pixelation on several channels. However, the BBC channels and all HD channels are fine.
(I have a roof ariel).

looking at signal strength through my tv menus i see that the BBC channels have good strength but the others eg stv, channel 4, channel 5 etc have weak signal and bit errors.
Looking more closely I see that all the poor channels belong to Multiplex TSID 2011, ONID 233a on the Network Central Sc (ID 3048).

According to all my searches there are supposedly no problems at Blackhill or work going on. Is anyone else having same issue. Are they working on this multiplex? STV is weak but the STV HD on a different multiplex is fine. Dont know if I have an ariel issue but my BBC channel signal strength is v high according to my telly!

Any help or advice please, these problems started a few days ago and its now 26th March 2017
