The Tower lives and grows

BT Tower, 47 years and still going strong

Transmit til it megahertz, 47 years and counting.

It is such an iconic part of the London skyline, central to telecoms, and in particular television development in the UK.

I have a soft spot for the BT Tower / Post Office Tower. I gaze up at it. I watch it. I take photos of it.

When the antenna galleries were stripped of all the original (and subsequently added) microwave aerials at the end of 2011, I wasn’t the only one worried we were at the end of an era for the Tower.

In an era before fibre optics and before satellite transmission really got going, you moved signals across the country in point-to-point hops from one transceiver to the next, and the Tower was the centre of the network.

But I’m pleased to report a small return to form. The picture on the left I took in mid April 2012. The picture on the right was taken on 2 May 2012.

Spot the difference (apart from the weather) There’s a new white microwave antenna – the tower is beaming long-distance signals again! 47 years on, it still performing its original purpose.

Interestingly, the new dish isn’t located in the traditional gallery, but much further up the tower which means it probably has a range of around 25-30 miles depending on the power output. It’s facing west, which takes it out to about Slough.

The diameter is about 2 meters, so a significant sized dish.

It’s highly likely that this link is being used by a company other than BT, but if you know any details, let us know in the comments.
