By providing a full postcode (such as W1A 1AA), national grid reference (for example SE123456) or latitude, longitude pair (like 54, -0.5) this page will provide a map, terrain plot and detailed information of the location showing the UK and RoI television transmitters that it is possible you receive Freeview, Freeview HD, Youview, BT Vision and Saorview from.
 

(Don't know your postcode? Find it at Post Office Postcode finder).

UK Free TV uniquely shows you transmitter coverage maps, aerial to transmitter terrain plots, the closest 10 mobile phone masts (for possible 4G-at-800 interference) as well as tabulated information (sorted by direction, by received signal strength, by frequency, by service names or by transmitter name).

Ron: Hi, Ron. I have a number of different DAB radios, some of which are made by Roberts Radios Ltd. In order for you to get help from this website, we need you to provide the postcode of a building on your street or road, such as a shop or a post Office or a Garage. Alternatively, you can give us the name of your district or village. This is so we can look up which transmitters cover your locality, and then we can suggest things that you can do to get and/or improve DAB reception on your Roberts Sports DAB radio. Hope to hear from you soon, Richard, Norwich.

Andy:

I suspect you have an incorrect understanding of how electricity works. At a given working voltage, the design of the electronics will determine how much current is required to be consumed.

The masthead amplifier requires a certain voltage and will consume up to 65 mA current. From your figures, the SLX distribution amplifier will provide the correct voltage but can only deliver up to 25 mA current - which is well below that demanded by the masthead amplifier. That means the SLX is *not* suitable as it cannot deliver sufficient current. As jb38 says, it is likely to mean the SLX fails. The only solution is as jb38 suggests.

Hint: remember Ohm's law and the formula for DC power P (power) = I (current) x V (voltage).

MikeP: jb38 thank you both for your replies, much appreciated.

Mike you are correct I could do with learning more about electricity, I am somewhat lacking in this area!

When I took a look at both the SLX and the Masthead amp It did get me thinking that things didn't seem to match up.
like I say I am no electrician but I did think that the numbers didn't seem to add up and it was my concern that if the amp is overworking the SLX that it may fail, I was even more concerned that its up in the loft that does get very hot in summer and the thought of it being over worked and in heat leaves me feeling a little uncomfortable! hence me asking you guys that know considerable more about this subject than me!!

Not sure what you guys think about my plan, please feel free to correct me if incorrect on anything, my main aim is making sure the setup is safe and will deliver years trouble free service.

The SLX has been in the loft for a long time buy the looks of it so I was thinking of replacing it with a newer updated possibly safer distribution amp, obviously I need to make sure a new distribution amp has line powering and is capable of supplying the Masthead amp with the correct current, keeping in mind that I have a Vision Masthead Amp (that's is new! and very low noise) and I am really pleased with its performance I was thinking about replacing the SLX with one of these -

Andy: after reading all your posts, you said you had 90 dbuv at the aerial head, you don't need a masthead amp or a distribution amplifier, at those readings I could put it into a 12 way splitter and expect perfect reception on all TVs. If you have perfect line of sight to winter hill all you need to run 4 TVs would be a basic 12 elements aerial and a 4 way splitter. Sorry but you have been ripped off.

Just been looking on line, I think this may be a more appropriate replacement?

PROCEPTION - PROAMP24 - AMPLIFIER TV AERIAL 4 WAY | CPC UK

I think this fits all the requirements of the Masthead amp if I have understood correctly?

Andy: Yes! the Proamp24 should be a perfect replacement for your SLX, its 100mA line feed output being exactly the same as the rating on Vision's own power supply.

However, as the Vision variable gain mast head amplifier is capable of providing up to 27dB gain at maximum advance, I would advise backing it off to the minimum (15dB) when first setting it up, checking the signal strength levels on each of the muxes received, then if necessary, advancing it as required.

The only reason for suggesting this is to avoid the possibility of signal overload on the tuner, as the total gain of the system will already be 24dB at minimum level, the Proamp 24 having added 9dB to the output of the Vision
mast head unit, and although you are located at approximately 38 miles away from the Winter Hill transmitter, a terrain check indicates that you are line-of-sight to same.

jb38:

Thank you again for your advice, very much appreciated, totally get what you are saying, I will set the masthead amp to its lowest setting when installing the Proamp24 and go from there, I certainly don't want to end up overloading my tuners!

With regard to The Winter Hill Transmitter and the terrain check indicating that we have line-of-sight to Winter Hill that isn't quite correct, where we live we are surrounded by BIG tress to the North, west and east, I have been unable to achieve a useable signal from Winter Hill, I have tried everything including a phased array and an XB16 along with amps but still the quality of the signal from Winter Hill was erratic, Even worse if the trees are wet and more or less the signal disappears completely if its windy and wet!

Bear in mind we live in a listed building and a conservation area and all signs of the 21st century are banned, we would require permission from a number of bodies if we were to install an external aerial and even then we would be restricted regarding location of the aerial, hence why my aerial is in the loft!

When we moved in the Aerial that was already here was a contract Group B positioned on the Mole y Parc transmitter which worked ok ish, however the programing is somewhat different in wales from that of the English regions so I decided to try and get our signal from Winter Hill but like I say that was unachievable and unusable due to the quality dropping out constantly.

I went to this site and found that The Wrekin transmitter was available at this address, I bought a XB16 Group K set it up on The Wrekin and have had spectacular results, I get a good, clean steady signal on all muxs from the XB16 K on the Wrekin and it hasn't blipped once since I installed in about 2 months ago :-) in fact its the best quality signal we have ever had! I was well pleased with the results :-)

The Wrekin aerial is fed into a diplexer and then into the Distribution amp, (no other amplification required as the XB16 K is delivering full quality and 85% signal :-) dam good aerial, either that or we are in a strong stop for The Wrekin!) The masthead amp is on a group E aerial on Winter Hill which is also into the diplexer just because Mux 1 from Winter Hill is just about ok, you can watch it as long as you don't mind a few blips! I just kept it as I know BBC NW covers us on the weather map, I not a news watcher but if I want it its up in the 800s.

Sorry I have rambled! off to order Proamp24 and I may order a PROception Masthead Amp why I'm at it, just to see what its like compared to the Vision amp :-) I am really getting into this world of RF :-) I have so much to learn though!!
Thank you again for your advice much appreciated. Andy

Can anybody help me. Recently we have lost Radio 4 FM from our local transmitter, Cambret Hill, South West Scotland. Going through all the usual website and phone links gets nowhere. No faults are listed for this transmitter. I just want somebody in BBC engineering to agree there is a problem and let me know when it will be fixed.

John McQuistan: Hi, John. Here is a web link to the BBC Contact Us page. I have used it myself and someone responded in a day or two...

BBC Form - BBC - FAQs - Home

Remember that the BBC is responsible for dealing with reports of losses of programmes for transmitters, even though they'll probably get the transmitter engineers at Arqiva to deal with it. Arqiva's telephone number is 01962 823434, but there probably won't be anyone to answer your call until Monday morning. Also, have you tried receiving BBC Radio 4 Long Wave on 198 kilohertz Long Wave? AM reception should be OK from the Westerglen transmitter near Falkirk for you because long waves travel a long way, anyway. Richard, Norwich.
