I watched a video on YouTube about the upgrading of Redruth
transmitter in 2018, which may be of interest to the group:
https://www.youtube.com/watch?v=kZtEbP3GB_0

They used a helicoper to remove two large pieces (presumably antennae)
from the top of the tower then delivered a replacement. As I watched
I wondered how did these items get there in the first place without a
helicopter - or did they use helicopters to build these transmitters?

Good, thanks. I shall read that with interest. Before spoiling the
plot, my guess is that they would build it horizontally then raise it
to the vertical position.

I think such kit is lighter now than it used to be, so I doubt they could
use a chopper.
All of this transmitter talk made me think of the ones in SW London, in
Croyden/Crystal Palace. These are old fashioned lattice masts built on
assumes in similar manner to pylons. I wonder if they are being looked after
as they are very close to buildings, and I'd hate to see anything drop off!

Older pylons were quite flimsy, we had a few sites that used pylons -
Hydro Electric had lots of pylons so why buy towers! They were
eventually changed to modern towers - one was then declared unsafe and
no one was allowed to climb it. You could easily see how much flimsier
it was than later ones and could shake it!

I don't think it mentions that the UHF antenna was often hoisted up the
middle of the tower straight into the fibreglass cylinder on the smaller
towers but when our local one was replaced, the whole antenna was lifted
into place with a crane - the old cylinder became a drainage pipe under
the track!

Right enough; you would need to install the first bit securely before
adding to it if 160 tons are involved. You certainly would not be
lifting the completed mast with a Chinook.
