Freeview Aerial Feed Question

Hi,

I'm planning my options at the moment which include a new tv aerial, so I have a question about Freeview receivers - do I need 2 aerial feeds to my tv - 1 for Freeview and one for Analogue (I want to keep my options open as I'm in an extreme fringe district - strictly no reception but special aerial might just pull something in) or does the Freeview box feed out or have an analogue output that feeds out analogue when the digital box isn't in use?

I need to know this so I know how many splitters I need and where to site them - I'm kind of hoping that the Freeview box has some kind of analogue output when turned off but don't want to just presume this!

Thx.

All freview boxes have in/out connections for RF aeriel connections which loop the analogue signal through the box and into the tv .The digital signal is picked up from the externel aerial lead and the pictures are then fed to the screen via scart lead in most cases(i have seen a freeview box with componet outputs).

Your tv will still pick up analogue tv with the box switched off,but as for your aerial i would speak to a specialist retailer about the best one to fit or have fitted for your area

Hope this helps.

Thx Steve.

I'm going to try a Televes DAT75 with MRD and PSU. It's 7 feet long, 75 element and has a 32db gain (!!!!!) with MRD fitted (19db without).

Its the aerial that an Australian scientist used to bounce tv signals off the moon!!!! I've heard it said that its the most powerful aerial in the world and is the only aerial to have CAI Cat 1 status in the UK to my knowledge. I'm kind of thinking if that can't bring it in then nothing will!

I think I'll go BBC Freesat next year but ideally would like 2 different aerial sources just in case bad weather or other causes one or more signals to drop out - I know 2 feeds are usually normal when Sky is fitted as my friends have Sky.

Also land the Space Shuttle and play a significant part in the SETI project.

Don't think I'd want to risk it in the Highlands of Scotland where I live!

We can get some mighty gales!

Looks like it might take the house along with the chimney!!!lol

Thats why after one did in The Great Storm (Michael Fish etc) we moved our aerial off the chimney and onto a 1.5 inch diameter pole on brackets on the side of the house.

Actually its not as bad as it looks as I'm going to be needing vertical polarisation as well which means that when its mounted side on theres a lot less of a profile.

That said I saw one in Newquay Cornwall on the side of some apratments during a gale and it held up well. So hopefully all is well!

That kind of reminds of the Only Fools and Horses episode where Del Boy's satelite dish guides the 747 towards the flats!

I've recently purchased a small TV that can receive Freeview - except for the last couple of months it can't because of leaves on trees nearby. I'm going to have to either move the aerial or do down the Freesat route - which I'd prefer not to do.

If I bought a new aerial (something like a Televes DAT75) and moved it furher down the garden the cable run would need to be about >60 metres. The aerial would still need to look through a row of conifers anout 200 metres away, but not through the middle of a huge horse chestnut tree as well.

Question is - and assuming a very good quality cable - would the Freeview signal survive a >60 metre cable run ?

I live about 30 miles SE of Sutton Coldfield.
