Re: 405-Line VHF Aerials 2013 to the present day.
One of the TV's upstairs at what was my Grans would sort of work on digital with just the aerial lead connected and going nowhere (Bushfield Rd. Crewkerne, receiving Mendip) and in another room a loop antenna fixed to an old Fidelity CTV could receive digital before switchover.
I also remember going to an engineering training place on the Granby in Weymouth/Chickerell and whilst waiting to be picked up watching TV on an Amstrad TV/VCR with no aerial socket! (it had broken off), I know that the Weymouth transmitter in Wyke is very strong there. |

Re: 405-Line VHF Aerials 2013 to the present day.
We used the Wyke transmitter here on the east side of Charmouth for a while until they put in a repeater on Stonebarrow hill. We had a problem with it though, at certain times of the day BBC2 would fade out for a while, we came to the conclusion that it was 'tidal fading' at certain tide heights you would get an anti phase signal reflected off the sea.

Re: 405-Line VHF Aerials 2013 to the present day.
Seen yesterday in Bristol, on the roof of what is now a Polish 'corner-shop'.
The short-ish BI single-dipole, and orientation of the BIII elements [which couple to the BI dipole] suggests it was once tasked with receiving BBC from Wenvoe and ITV from St.Hilary from across the Bristol Channel.

Re: 405-Line VHF Aerials 2013 to the present day.
Doesn't look like it was in one of the more
difficult reception areas in Bristol. |

Re: 405-Line VHF Aerials 2013 to the present day.
It looks like this was aerial is in a good reception spot for 405 line TV reception. BBC1 from Wenvoe on ch5 and HTV on ch10 from St Hilary.
On the whole 405 line reception from the transmitters, both located in South Wales, across Bristol was pretty good. I think the bad or black spots were covered by cable TV.

Re: 405-Line VHF Aerials 2013 to the present day.
Spotted this "new" installation last Sunday in the soon to be opened 50s section at the Beamish Museum.
Are they hoping for the resumption of 405 line transmissions? Keith |

Re: 405-Line VHF Aerials 2013 to the present day.
I think it also helped that the Avon Gorge or the River Avon valley went the right direction enabling both VHF 405 line signals from St Hilary and Wenvoe to propagate into and across Bristol.

Re: 405-Line VHF Aerials 2013 to the present day.
It could be but the nearby Pontop Pike Band 1 transmitter was on channel 5 and horizontally polarised.
The ITV transmitter was at Burnhope, also not too far away, and was opened in 1959 so that house could be dated to the very late 50s. We're planning to return sometime in May to see the new section. Keith |

Re: 405-Line VHF Aerials 2013 to the present day.
Yes it occurred to me after I wrote that could be the case. In Kent we were on channel 1 Alexandra Palace then Crystal palace and our dipoles were nearly 11' long so never came across Ch5 or horizontal band 1 antennas.
Thinking about it there is only about 10 mhz difference between the top of band 1 and the bottom of band 2 so could be either. We will see what's connected to the other end of it when we go. Peter |

Re: 405-Line VHF Aerials 2013 to the present day.
It doesn't look as if there's a cable connected to either aerial. Perhaps it's still Work in Progress!

Re: 405-Line VHF Aerials 2013 to the present day.
The larger of the two aerials appears to be rotated thorugh forty-five degrees which I would expect if it was a FM aerial?

Re: 405-Line VHF Aerials 2013 to the present day.
When I was a young child, the skyline of Dublin was crowded with enormous aerials, typically a 5-element Band I pointing north for BBC1 from Divis and a 12-element Band III pointing east for HTV Wales from Arfon. After restrictions on cable TV were relaxed in 1974, 'piped' tv quickly spread across the city and such aerials became largely redundant.
There are a few still around, typically now toothless affairs with most elements missing. It was therefore a pleasant surprise to find a relatively intact example on the roof of a 1960s-era nursing home recently in the north Dublin suburbs. In this case, the Band III is pointing north for UTV from Black Mountain, which possibly offered better reception at this particular location. |

Re: 405-Line VHF Aerials 2013 to the present day.
Was it really for reception of british transmitters ?
I thought the 405 lines TXs were all in vertical polarisation ... |

which these were aimed at. East Anglia was a horizontal area as was the Northeast. A lot of the band 1 low power relays were horizontal as well. |

Re: 405-Line VHF Aerials 2013 to the present day.
Arfon on Ch 10 was also horizontally polarised, and such aerials were were common in Dublin. As a kid I remember the first time I saw vertically polarised aerials directed at Brougher Mountain on ch5 and thinking 'why are they the wrong way around?'!.

Re: 405-Line VHF Aerials 2013 to the present day.
I think the amount of survivals of large 405 line TV aerials is a testament to the quality of installation work at the time. Definitely not bodge it & scarper!

You're right, all the pubs seemed to be using cable by then, but the hotel at Dublin airport seemed to be getting a UHF off air feed from Divis for some reason. |
