Re: 405-Line VHF Aerials 2013 to the present day.
I remember back in the 60s swapping "biscuits" in the old clunk-clunk rotary tuners so Sutton Coldfield [4V], Lichfield [8V] and Winter Hill [9V] were next to each other.
Back then most people had separate antennas for Lichfield and Winter Hill [inconvenient geography put the transmitters at 90 degrees to each other] so it was normal for there to be three coax downleads... one for BBC, two for ITV. I made up quite a few switchboxes using a simple toggle-switch fitted in a 3-way BESA box so people could switch between their two ITV antennas. |

Re: 405-Line VHF Aerials 2013 to the present day.
On my first portable TV, BRC980, which used a rotary turret tuner, I had the biscuits moved. The ch9 ones swapped position with ch12.
Where we lived in west Cornwall BBC1 was from either North Hesssry Tor (ch2V) or Redruth (ch1H) with ITA from Caradon Hill (ch12V). It saved a lot of strain on the mechanics of the tuner and your hand.

We used Stockland Hill on channel 9, same frequency as Croydon/Crystal Palace which we received in Kent.

Re: 405-Line VHF Aerials 2013 to the present day.
Spotted today in "Old Town" Swindon - this BIII array points North-West.
I guess it was for St.Hilary, One reflector has entirely gone-missing and bits of the directors have opted-out too. |

Re: 405-Line VHF Aerials 2013 to the present day.
This one's visible from the "Robin Hood" roundabout in Newbury.
The vertically-polarised dipole-and-reflector H [missing a top leg] points due-East to get London BBC; the horizontally-polarised Band-III array [with interesting design of folded-dipole] points West-with-a-bit-of-a-North-skew to get the Membury relay of Sutton Coldfield ITV. |

Re: 405-Line VHF Aerials 2013 to the present day.
Re post no. 789:
G6Tanuki - the Band III is an 8 element Antiference, possibly a later version judging by the junction box, with Antiference's 'Trumatch' dipole. I don't know about the Band I 'H', other than it is unlikely to be an Antiference one. Whether the Band III aerial is actually for Membury (channel B12, Horiz) or is one originally for London's Croydon Tx (channel B9, Vert) that has been 'swung', is an interesting question. Many aerials were so 'repurposed' in high field strength areas where ghosting was not a problem, even though they many not have been designed to cover the new channel.

Re: 405-Line VHF Aerials 2013 to the present day.
Membury is actually east or southeast of Swindon located just along the M4 at the nearby services. My guess is the aerial has been blown around or its a ch10 aerial for St Hilary that has been tilted by the elements.

Getting St.Hilary in Newbury would be a serious stretch; it was a struggle to receivve it even in Swindon; Newbury's 25+ miles further-East and with the chalk-escarpment of the Ridgeway intervening to add loads of extra path-loss. I do wonder if the BIII antenna had originally been vertically-polarised and pointed towards Croydon for London-ITV, but was then swung to Membury when it came on-air. But Membury was always a relay of Midlands-ITV from Sutton-Coldfield, and I really doubt the residents of Newbury - only 50 miles from London - would have found ITV News featuring reports from 140-mile-away places like Derby and Mansfield to have much interest. |

Here is another one from Donny.
The ITV is pointing vaguely south. |

Re post no. 793:
It is hard to tell but is the Band I aerial an 'X' or a 'K' ? The Band III looks to be an early model with that type of construction - whose make I don't know. |

Re: 405-Line VHF Aerials 2013 to the present day.
Membury was an interesting transmitter extending the Midlands region way south into the London, West and some of the south regions. I think the ITA were more interested in providing an improved service to this area which was on the fringes of the service areas of Chillerton Down, Croydon, Lichfield and St Hilary rather than the regional programmes it carried.

There is an "X" that has collapsed onto the roof in the town centre. I have just looked at my attachments from around the time and it is not there. |

Re: 405-Line VHF Aerials 2013 to the present day.
The "X" looks like it had a couple of new pieces on it sometime or other.

It might be shadows as the sun is coming from the left and was quite bright.

Re: 405-Line VHF Aerials 2013 to the present day.
Could be shadows , it just looked so clean, although I agree it would be a bit odd if the element(s) had been replaced.
