Is your TV a full HD type? Vintage TV is now on an HD only multiplex so to rteceive it you need a full HD set. An 'HD Ready' set does not have the ability to receive HD signals on its own, you would need to add a Freeview HD set top box!

The Belling style coaxial plugs are not the problem but it is the way someone has wired it up that is. It is a simple matter of ensuring that the centre conductor is fitted properly into the centre pin (and tightened correctly if it is of the screw type or soldered if it is of the older style) and ensuring that the outer braiding has been opened up correctly and wrapped around the compression collar so that it makes good contact with the main body but does not leave any fine filaments free to touch the centre core. Over my years in the industry I hate to imagine how many thousands of these I have fitted and re-fitted. The plug is not the problem then, but fingers and bad workmanship are.

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).

Add your full postcode into this website. That will enable the 6 banners across the bottom of your posts. They all relate to your reception of Freeview and the DigitalUK option gives the compass direction you seek.

It is quite likely that the engineering work is the cause of your problems, though we cannot be certain as you have not given a full post code. Signals are likely to return to normal once the work has been completed, but there is no indication of when that will be.

As it states near the top of this page, Vintage TV is now on COM7. This is an HD multiplex so you need a TV, or set top box, that is equipped with a DVB-T2 tuner. The TV, therefore, needs to be a Full HD type and not an 'HD Ready' version.
You also need to live in an area served by a transmitter that carries COM7, not all do. To find out if that is available where you live, put a full post code into this website and check the little blue box below your post that shows the title 'digitaluk trade'. That lists the transmitters available in your area and will tell whether or not it carries COM7. If it does and your TV is a full HD type then you should be able to receive it, maybe needing a retune. If it isn't on your local transmitter or your TV is not a full HD type then you will not be able to receive it currently.

To answer that we need a full post code, just the first part is not enough to trigger the details.
Note though that the Winter Hill transmitter is listed as possibly being on reduced power, which often causes TV sets to complain of no signal.

Heathfield does not as yet transmit COM7, hence the lack of it in the area. I suggest you ask Arqiva, who are responsible for the transmitters, when or if Heathfield is likely to get COM7.

Rather depends. If there is already a working satellite dish fitted then Freesat would be easy to set up with a suitable receiver or box. If not, then check if there is already an aerial system available. Note that many blocks of flats use a communal aerial system, so check with the new neighbours (a good way to start getting to know them) whether they have their own aerials or use a communal system. If it is communal, then just plug in the TV and do a full retune. Note that you would not be allowed to fit your own aerial system without permission from the building owners or the Management Committee, so check with them before doing any work.
If you take a look at Which Freeview channels does the Kendal transmitter broadcast? you will see that the Kendal transmitter is of the 'Freeview lite' tyupe, meaning it does not carry the full range of services found on the main transmitters. If you put your full post code into this website, you will eventually see a set of 6 blue boxes below your postings. One of these named digitaluk trade will list what transmitters can be received at your location, what the channels are and what direction the aerial should be aimed to get the best available reception. It will also tell you what type of aerial to use, if you need a new one fitted.
Hope that helps you get started?

Alan Goss: you shpuld never connect two, or more, TVs to the aerial system via a passive splitter and certainly not when your signal levels are so low. All the splitter will do is reduce the signals strengths even further - by anything up to 2/3s!
I concur with the comments from jb38 and MikeB. We really need to have a full post code (or that of a very nearby shop/post office/public building) so we can determine what would be a good reception for your location.
