Default Re: Your best preserved '405' aerial

I have just checked the "H" aerial in my loft as mentioned in my last
message.
It measures just under 10 ft and the centre part is about 3 ft.
Made by Belling Lee ?
It has a small PCB with a couple of components on it which is connected
to some coax cable.
In very good condition.
Any idea what it would have been for?
I thought it may have been for TV reception originally.
Anyway , If it is of use to someone let me know ,
Free to collect to first person who may want it.

More spotted 405-line era aerials for you to enjoy. I took these in Coldstream in the Scottish Borders yesterday and what whoppers they are!
The first pic shows a ch5 Pontop Pike and ch8 Burnhope set up with added BBC2 aerials for Chatton and Selkirk. The second shows a 3-element ch5 Pontop Pike aerial and ch13V Selkirk BIII. The third is a set up for both ch 5 and 8 plus a vertically polarised ch13 aerial for Border TV Selkirk.

Cheers!

Brian

There used to be a few horozontal B1 Dipoles and H aerials down in Cornwall pointing towards the Redruth transmiter.
Let us know when you take a closer look at that one in South Petherton.
There are still a few X and H B1 Wenvoe aerials around this area, but they are gradually dwindling in numbers now. Its amazing to think what good coverage they had using Bands 1 & 3 compared to the UHF bands, Wenvoe ch5 I know reached parts of North Cornwall and into parts of Dorset.

Spotted at Kelso in the Scottish Borders yesterday, this magnificent 4-element ch3 structure for Kirk O'Shotts. Unfortunately it seems the corresponding BIII aerial has been removed to make way for UHF arrays!

Some BIIIs in the area have survived although unfortunately the Band 1 beams had long broken off.

Cheers,
Brian

Well I've been to Matlock Bath Derbyshire today and while snapping away at a few points of interest I also found a few examples
apologies in advance for the lousy photography
not sure if the first one was a band 1 or a band 2? but it was very big

Hello,
The area around Guildford is a good hunting ground for 405 aerials. There are quite a number on the approach along the main A281. I have noticed this fine array hidden on the roof of a very old house with its front porch almost overhanging the road. Anyone familiar with the area will know it well. I parked the lorry up causing a bit of a jam but all efforts must be attempted for the forum! As can be seen the 'X' has come adrift but is still connected to the cross over unit. A short length of feeder can be seen at the bottom of the pole. I wonder what set it connected to? Regards John.

Hello again,
I just had to post this lot on the roof of a terraced house situated at Broadbridge Heath near Horsham. It appears to cover the whole spectrum!
One UHF array points to 'our local' transmitter at Midhurst. Another to Crystal palace with mast head amp. A band 3 array that looks quite fresh lined up to Croydon. A band 2 F.M. 'halo' and a mini dish! Regards John.

Having finally finished the film in my camera and getting it back today, here is my "Johnny-come-lately" contribution of three "405" aerials in Cockermouth, Cumbria. Unfortunately, the second and third are a little worse for wear.

Coming from London it's quite weird seeing Band 1/3 aerials with HORIZONTAL polarisation. I seem to pass a fair number while travelling around London but never have my camera with me. I guess my anorak is too clean

Yes, I'm more used to seeing the band I aerial as a vertical "H", as I was living in Oxford in the days when these still had something to "listen" to. The band III aerials were horizontal though. If I remember correctly, we received BBC (band I) from London and ITV (band III) from Birmingham.

Hexham is a great location for surviving BI/III aerials such as this example I snapped today. When reflected in the sun it looks remarkably clean!

Love all the other photos!

Cheers,
Brian

I would guess the horizontally polarised BIII aerial will have been for Membury ch12, which carried ATV Network programmes.

Caught this wonderful combined ch5/8 array still standing in Durham City. The top UHF aerial has worked loose! These combined types were very common in Tyneside, the BI dipole doubling as a BIII one with "loops".

Wonderful!

There's one on top of Darlington bus station!! Sadly it's now a bus depot no longer accessible by the public. I thought it was the only one in the north, obviously I am wrong.

I think those were the channels which we picked up in Oxford, at least before the Beckley transmitter. One puzzling thing, though - these seem to pointing southwards (although they may have got twisted round in the last twenty or so years!)

The UHF yagi is pointing at Beckley (NE from Binsey Lane).

Ah yes, I remember the band III with a skeleton slot - had one on my primary school in Danehill, Sussex, (with an 'H' for band 1)as I recall! (aiming at Croydon and CP)

Here in Ireland, band III is still used for 625 RTE, and there are also a large number of old 405 aerials around, as everyone here erected large aeriels to pick up UK TV. There are privately owned UHF repeaters or 'Deflectors) as they are knowm, and the government was forced to licence them about ten years ago, as a couple of independent MP's were elected on a single issue TV deflector stand!)
attached is a recently taken photos, one of a 405 line aerial taken in Donnybrook, Dublin., one of a huge parabolic UHF receiving aerila for a deflector,from the late 70's early 80s located near Cashel in Co Tipperary, and also a current band III slot aerial which looks like it is a copy of the antiference slot mentioned above. I would be interested if any one access to one of the aforementioned slots I would appreciate some dimensional measurements, as I would like to add the directors to one of the Slot ones shown, as my RTE from Mt Leinster here in Tramore suffers from multipath a bit - I have an Antiference log periodic up at the moment, but its not great in the gain department!
I will take a few more photos of some 4 elly band 1 aerials still around soon (before these wids knock them down for good!)
