I bet people in strong signal areas carried on using them for 625 UHF. Just a thought, in a very strong signal area would it be possible to receive a modern day digital TV signal good enough to get a picture?

Even close to Winter Hill, the early sets had valve tuners and the NF at the top end of Band 5 was poor, needed every bit of signal to get a snow free picture. Transistor tuners were a great improvement.
No doubt some could get by with the wrong aerial but we couldn’t from Winter Hill and it was line of sight.
In 1969 when all 3 stations were on UHF we usually fitted a new aerial with a new set.

Thanks Frank. I was just trying to say that I bet some people, signal level allowing, simply carried on with their old VHF aerial if they could get a picture.

Hi Steve,
On the lower frequencies of Band 4 it probably did occur, especially with transistor tuners. We had quite a lot of fun and games in the early days get noise free pictures on Band 5.
Philips valve tuners seemed to perform better than those from RBM and Pye.

Certainly, when we lived in Durham, not far from Pontop Pike and Burnhope, BBC2 reception was awful from the attic VHF aerial. Chs 5 and 8 were received perfectly however. So, despite the horizontal mounting, a UHF aerial is/was a must.

Funny to think years later, reception of ATV from Oxford UHF was better on a fixed six element Band 2 aerial than it was from a UHF rotatable one which was a bit odd!

The following photo was taken, whilst stuck at temporary traffic lights on Muller Road, Bristol last Friday evening.

It is an aerial I have noted for years, to me a local landmark, and I'd notice it straight away if it ever disappeared ! Have always looked up at it, even though my eye should be on the road!!

It a Band 1 VHF TV aerial, that would have provided its household with BBC 1, from Wenvoe, before we had the Mendip transmitter of 1970 to serve us in Bristol.

Not sure of the make - a sort of folded dipole arrangement, which I used to see a lot of in Bristol in my childhood - possibly Telefield, a local manufacturer, now long defunct, from 259 Kingsland Road St Philips, Bristol ? - Does anybody else recognise it?

The two contract style UHF aerials on the neighbouring property, pointing to Mendip, I guess were added to an existing mast, (now truncated) which appears to be 2" diameter - I guess when first added to this mast, the mast may have supported a larger VHF array further up top.

Looks in remarkably good condition for its age. We used to receive mendip down in Charmouth. When Stockland Hill went UHF you couldn't get a decent signal down in the town because of severe ghosting. They put up a tower at 'Stonebarrow' on the cliffs, received a signal from Mendip and converted it to VHF, it was distributed by a wired system called 'Viewline'. They also had it in Lyme regis and Beer.

Of course you needed a dual standard set to be able to receive it. There is now a Stockland Hill repeater on the site.

I see one of these band 1 Wenvoe ch 5 aerials on my way into work. Its in Bitton on the A431 Bristol to Bath road. It seems to be holding up very well whilst the band 3 ch10 St Hilary aerial has more or less gone with only a few bits to be seen.

A nice array in Newport Pagnell and in very good condition too

Spotted during one of my early morning runs a few weeks ago...

I know of at least another two in the town but they're hard to photograph with my limited photographic kit and talent...

This amazing structure is still standing in the heart of Bath, exactly as it appeared in this photo taken a few years ago.
Wenvoe ch5 and St.Hilary ch10.
