I have just got a freeview box and have quickly found out why analog is better with an indoor aerial.

So I have to put an aerial on the roof to ensure a decent picture.

Any advice on types of aerial and best direction to get the best signal form the transmitter?

I mean how hard can it be?

(pobably harder than I am imagining)

Thanks

If it has to be on the roof, get an aerial rigger to do it... it's cheaper & less painful than breaking your neck...

And the rigger will know where to point the new aerial, though looking at other aerials in the street is normally a good indicator of the direction of the transmitter.

My Sky dish is on the chimney, which is highly convenient since the LNB died.

I'm not going up there & not paying anyone to do so, so I've got a dish looking out through the boxroom window.

Works a treat.

£15 from Lidl, plus £3 for the new LNB.

Maplin have a reasonable range of aerials, and this one might be suitable.

As Zeitghost said, you can get some idea of the size and direction of aerial required by looking at several in your area. A booster amp might help if the aerial doesn't have enough gain.

If the aerial doesn't have enough gain, buy a bigger aerial... it's cheaper than running a booster amp... though saying that, I have a booster amp with my freeview box in a vain attempt to reduce the patterning from the box on local BBC2...

Now I know why the Panasonic box was cheap in Argos.

Largely because it radiates all over the UHF band...

Fixing a roof-mounted TV aerial isn't difficult: ask Rod Hull

We bought a new TV and DVD recorder recently. Both with built-in freeview. In one of the manuals it mentioned that you can put big aerials in the attic and they should work well. Lot safer/easier to do, though no idea if the reception is as good.

Hi qerry. I have tried it in the attic but its just not a good enough signal but maybe thats due to the small ariel, not to mention the dodgy floor up there. There is a bloke who said he would get an appropriate ariel and install it for £60. He hasnt seen how high our house is yet though.

Hi mr bwts,
Gerry is right, I think. I know a plumber who did aerial rigging years ago: He told me 2 things which I've always been grateful to him for:
1. Most aerial riggers have the IQ of a hamster.
It isn't rocket science and most of them cut corners which, if you do it yourself, you won't.
All they have which you dont is a head for heights. With proper ladders you should be OK. I also do a touch of climbing, so I have a handfull of caribeeners and harness which is cheating a bit. But if you put a hook or somesuch in the wall, you can at least fix it so the ladder wont slide off sideways. A very important point, which injures lots and lots of ladder climbers every year, is to make sure the bottom of the ladder cant slide away from the wall.
2. There's very rarely a real need to roof-mount the aerial. In low reception areas, or on bungalows, you have to because you have to use a 6 - 10 foot pole to get height. But, in normal reception areas, with a good , new aerial, it can comfortably go in the attic. If your attic aerial is naff, buy a nice new one with lots of reflectors. I bet that works wonders.

If you have problems getting a good signal you can do ehat I have done and get a second hand sat box for all the free channels.

You should be able to find a "kit" that will help in allowing you to mount it yourself. Normally, if you have a chimney, there are metal bands that go around the chimney, one up and one down. Those will fasten a mounting rod (vertical) to the chimney, then you fasten the ariel to the vertical rod.

If you don't mind heights, it's not that hard. Just some simple mechanical stuff. The reception I can't help you with as I'm across the pond and don't know a whole lot of what you're talking about.

Oh, a compass would help you point it in the right direction.

My dad used to put up tv aerials back in the 50s... Band One double H aerials at that...

Real Man's work up a ladder on a roof...

He also relates a tale of a mine manager up in Banwen (top of the Neath Valley) who was the first chappie to get a tv in the village, which "received" signals from Wenvoe on Channel 5.

It only required an aerial mast 70 feet high to get the signal in...

The mast was made out of jointed iron piping courtesy of the NCB... aerial direction being controlled via a 3 foot long stilson at the bottom of the mast.

There's tidy then... :o)

Only one channel, BBC, since ITV hadn't been invented quite yet around here in those distant days... along with a tuner reliant on the rf gain of an EF85, ECC89 or whatever...
