Might even have been installed in Ally Pally days before Crystal Palace took over.

Spotted this one on Tuesday in an older part of Peterborough. I had to stop as the road was unpassable due to the bin lorry stopping to empty bins. Due to this thread my eyes now stray to the rooftops...
If this is a band 3 aerial it may be the band 1 dipole has dropped off or maybe never installed. BBC on 405 was so strong in Peterborough a bit of wire poked in the centre of the aerial socket would do, so some houses never had a band 1 aerial as you could get a picture without one. Especially if the aerial was DIY installed. I had a band 3 aerial in the loft BBC came romping in. Most people were on UHF around here by the early to mid 70s I think.

I have trouble picking up AM radio in my flat due to the steel in the walls causing a Faraday's cage effect. Usually I have to leave radios on window ledges to get a decent signal.

That looks to me rather more like a mid-sixties Band-II FM antenna whose reflector has dropped-off.

The "Delta" stretched-folded-dipole design was no doubt touted as having some esoteric benefits regarding signal-capture/impedance-matching, but I think these were all marketing-nonsense trying to cash-in on the then-in-vogue swing-wing jet fighters....

It would make sense as in Peterborough VHF radio sets would have needed a roof aerial back then. Our first Music centre in the early 1970s needed a roof aerial to pick up stations reliably, by the late '70's the local transmitter, Morborne I think, was modernised for FM stereo after then no external aerial was needed so that old aerial has been redundant for a while!

Re post No. 923

I think the firm 'Maxview' made that style of delta dipoled aerials.

Back in the mid-1970s here in Cambridge, our only source of FM stereo was rather noisy DX reception from Wrotham in Kent. We had one of those Maxview jobs installed on our chimney. It worked well enough, but I suspect that the ‘Delta’ design was more for the benefit of structural integrity than signal performance. At least that one in the photo seems to have survived (almost) intact.

Photo taken on Newmarket, Louth, Lincs. 13/04/24. Nice survival of a (presumably) Channel 10 / UHF group A hybrid for Anglia on Channel 7, BBC1 North on Channel 13 & BBC2 North on UHF Channel 28.

Will be useful for DAB now I expect.

This photo was taken a few weeks ago. It is an Australian aerial, about 50-60 miles from Sydney - almost certainly for the old analogue Australian TV channel 2.

Phased arrays like this were very very common in fringe/out of service area.
They are failry wide band and use to serve for Band 1 - channel 2 & Band III Channels 7 & 9 (possibly 10) too.
Known as sky hooks .. often seen on 20m + masts/guyed poles.
There are forests of them in the suburbs of Bunbury (city) ~ 100 miles south of Perth.

Two examples spotted in Hanwell and Ealing today. 1/2 a Band 1 X pointing at Ali Pali & a Band 3 pointing at Croydon and an intact but slightly bent Band 1 X pointing at Ali Pali with a neighbouring combined Band 1 & 3 pointing at Crystal Palace. Happy to be corrected on either count. Apologies for the partially obscured combined Band 1/3.

I'm using a di-pole aerial in our loft for Freeview, reception I get as good a picture as I do on cable.

It looks that Australian aerial is a sort of VHF Band III (high-VHF) version of the 'Colourking'/Grid/Bow-tie array for UHF

4 horiziontal full-wave dipoles, with each having (to the right) one reflector (a 'grid' type reflector like the usual UHF version would be a bit unwieldly).
The downlead seems to be missing, suggesting the aerial is a long time disused.

In the UHF version, as well as a grid reflector, the (typical) 4 full-wave dipoles are 'bow-ties' (this gives wideband UHF coverage)

Hi, spotted this one in New Malden a few years ago, but have taken a picture last week. It is on the Cambridge Road kt3

Nice sighting!!

Good to see that this thread is still alive.

Have recently spotted a couple of old 405-line aerials in the Pangbourne area, didn't have a camera with me at the time but will do a drive-by in the next few days when I have a proper DSLR to take photos.

Oxford City Centre 2023:
A Band 3 aerial pointing north-west to the former Independent TV VHF main station at Lichfield, over 70 miles away. The remains of some additional elements (Band 1 for the BBC?) also present.
Lower down the pole, a very small UHF aerial pointing roughly north-east towards the main Oxford (Beckley) mast.

Beckley transmitted BBC on Ch2 with horizontal
polarisation from 1962 I think so the lower section remains of the vertical band 1 aerial
would predate that.
