All electrical items emit radio using exactly the same process that radio for transmission are created in the first place.

the radio waves are a crowded place and any body thinking they can just start willy nilly is under an illusion.
if a cber tries ramping up thier power it will inevitably spill over and cause a lot of difficulties A very nice easy installation on tapton hill transmitter today,with tapton in view and a signal of 89db it was what you could call a little bit easy.
with tapton hill transmitter in view and quite a nice part of sheffield with a clear day one of the commonest reasons for not being able to get sky are trees.
A sky signal will not pass through trees period,so one way to get round this a chimney mount,or a survey identifying other locations that can see the satellite. We use an instrument based on nautical sextant to check visibility ie elevation and azimuth. Without a proper survey you are left twiddling your thumbs if you decide to dump sky then your sky reciever can still pick up the free channels or freesat.
But if you have a sky + unit you cannot record on it without paying sky £10 a month. under these circumstances it would be simpler to buy a good freesat pvr and use that instead. cordless phones and blue enabled on your mobile can and will interfere with your terrestrial tv reception.
The cheaper cordless phones are very good at wreaking havoc,so if you have picture break up think back what new electrical or electronic equipment have you just bought If you want a bit of one upmanship consider a fully motorised tv wall mount.
they certainly arent cheap but you get a tv that wil be adaptable to your room and people watching the tv ,unlike the simple tilt brackets. prices start from around a grand but you dont anything good for a cheap price the back of anybody's tv is a jungle of wires and tends to be ignored but mains cables and tv aerial cables dont mix.
A digital signal can be quite delicate if especially if its been taped to a mains cable,try and ensure at least 6inches separation between mains and coax todays tvs are fairly complex beasts with numerous functions and options.
Some of these you will not need, but othera are interesting so take the time to explore the corners of its functions |
