we will be obtaining a nice new analyser in the new year so even in more depth signal diagnostics will be possible

ultimately a site signal state is ascertained by putting a tv aerial on a pole and connecting it to an advanced tv aerial meter,and looking for the best signal.
postcode predictors can only give a guide to a site most sky dish mountings are taken care off by the standard bracketary,however their can be occasions when the dish may need to look over a gutter or other obstacle.
There can be no one bracket to suit all eventualities hence we may well have to sometimes rig up a bespoke system with a spot of welding. Unless you have a total satellite obstruction we can usually get around any mounting situation a tv aerial cable as to come through a wall in some way ie a simple hole left raw or a cable hole tidy.
most people prefer a a co box or pattress box to tidy this up especially if it is visible to the room. of course the easiest way is through a wall from the outside. Fitting a cable into the structure of the house is a lot more involved involving chasing or running the cables in such a place where they are not seen. If your house is all new and freshly decorated then this is fraught with problems most people darent look behind their tv sets.
its a place where mysterious things take place and innumerable cables sprawl along with a mass of cobwebs. You would rather not touch it,but comes the day when you have to for instance a new tell or the dreaded decorating. all the cables do some thing so be very careful and a make a not of where everything goes,or we can come and sort it out for you the cost of a tv aerial point is dependent on your tv signal strength.
In technical term your signal needs to be at least 50db to split without using an amplifier. A tv aerial signal is a voltage albeit very small,but still subject to the rules of more demand on the voltage the lower each unit will get. we can quickly work out whether you need an amplifier with your postcode if you are a diy fanatic always equip yourself with a good metal detector.
Always presume there is something lurking in a wall,water pipes gas pipes mains cable they could all be there lurking waiting to drop you in it. Ther are a great many cheap detectors on the market that really are useless. A good detector is accurate and capable of placing your drill hole to with in 15 mil,these detectors sell for around £50 and upwards,expect to spend nearer £100 for a real rolls royce. I'm only going to use it occasionally you might say fair enough, drilling through a water pipe or gas pipe will cost you a lot more than that all digital tv and satellite units have signal checking systems built in.
whether it be your sky system or your freeview tv set this must be your first port of call,that is if you are ofay with getting to grips with some basic ideas. remenber rain will degrade your sky picture but it will only freeze if the rain is very heavy,or maybe your sky picture is just braeking up and giving you stress.Using the built in signal meter will tell you all you need to know. May we like the you view system,ok it is merely an enhanced version of freeview with an internet connection.
the internet side merely gives you access to a another stream of films and programmes. Couple this with a more detailed tv guise makes not a bad little package. make sure that you can receive freeview properly before committing to a package we seem to be getting a lot of people who signed up to it only to find there is a rather nice mass of trees blocking the view to the transmitter. |
