Hi

I've noticed that ALOT of people keep asking this so I thought I'd share the knowledge and that is if you want an aerial all you need is

(1) a Wire Coat Hanger (surely everyone must have at least one, maybe its hiding somewhere have a look about)

(2) a TV Extension Lead (everyone will have at least one proberly from an old vhs machine)

and its simple what you do next, Plug the wire into the Freeview box and the other end the Wire-Coat-Hanger slots into and once you move the coat-hanger about you will get a siginal and wala job done

before anyone asks if this is true or a load of bull try it out for yourself, it works, simple, nothing high-tech involved eh!

That'll do nicely if you're fairly close to the transmitter.

If you live further away, something a little more sophisticated may be needed. A dipole, a reflector and a few directors will give much better results if it's pointing in the right direction and is as high up as possible.

Get your UHF frequency band from http://www.wolfbane.com and then calculate the wavelength. 300 divided by the frequency in MHz gives you the wavelength in metres.

Each arm of the dipole should be just under half the wavelength. The reflector and directors are just rods of roughly the same length as the wavelengh. Arrange them in the same way as outside aerials. In most cases all the rods need to be vertical for main transmitters and horizontal for relays.

Mount the rods on something non metallic such as a bit of wood.

Connect the inner and outer of the coax to the two arms of the dipole. It doesn't matter which way round.

Be careful if you go clambering about in the loft. Obviously a homemade lashup won't usually be suitable for putting on the roof.

If you live too far away from the transmitter then a professional outside aerial is the only answer.

A very important correction to my earlier post:

Apologies for the mistake,

The question I ask myself about all this is: Do I really want to live on the top of a big hill (Sutton Coldfield, Emerly Moor, Wenvoe, Rowridge, Black Hill, Mendip) or under the base of some metal structure (Crystal Palace)

I think I stick with my DAT45 using it for the purpose it was designed....and my shirts well there all over the floor as I can't seem to buy a coat hanger anyplace!

It would appear as if there is a bit of a national shortage! There almost as rare as Rocking-horse sh*t, what with EVERYONE making there own TV antennas! And whilst we talking about that subject perhaps this whole thread is just Bull-Sh*t!

I got mine from a Pound Shop , its a cracking digital aerial , black base , sliver hope and two extendable antenna. plug it in move it around to find sweet spot and bobs your uncle.

I dont live under the mast , i have hills around me , i look out at tower blocks and trees .

And its nicer to look at than a coat hanger .

Get rich quick scheme

Keep placing posts on here of how difficult getting a Freeview signal is but lucky for you punters it just happens that for a meer £150 pound ill come round with me ladder and fit a £30 pound aerial and Cable kit . just out of the goodness of my heart. And you will get freeview then.

Go on you know its a bargain ....

i did this when i last went on holiday it was a communial tv aerial into all the rooms and it also had a couple of analogue satellite channels on it too and a channel which was a local radio station with a slideshow of things to do in the area playing. but the reception was awful in the evening and as there was a vcr i took the cable off the vcr that went to the tv and put a coathanger on the end and got a near perfect reception but without the extra channels they were sending through

I tried it out just now and it worked almost as well as my indoor Thompson indoor aerial. If i had a stable surface to put it on, I could use it as a normal aerial but I don't. What I have to say is that it works as well as and indoor aerial and if you want to save a couple of pounds, just do this.

You do realise, of course, that you've just completely blown your chances of making a fortune by selling this information to idio^H^H^H^H people on eBay for 4.99.

Sounds like the same ones I use. The shop I got them from was Poundworld (Cramlington Branch). I use one with my Compro DVB-T200 card in one room and one with a Oggle 3D Box (latest ASDA one) in another. I've tried several other indoor aerials and none have come close.

This is not right some relay masts use horizontal signals there is one near where i live which is horizontal which is a relay mast from winter hill.

Yes, fair enough, that's why I said "in most cases..." - John

Hmmmm.... The coat hanger aerial thing has been around for years and is nothing new... However the dat75 coat hanger thing has given me an idea...

If I was to use my freeview box as a hanger and as mentioned previously a coat hanger makes an excellent aerial ...... well you do the maths! LOL

Or use it for tripple decker, twin row tie rack.
DAT75 for double wardrobes and the DAT45 for single wardrobes.

Why not use a Coke can or something and connect it up to the coat hanger, provided that the can is made of steel as it is a better conuctor than aluminium.
