A month or so ago I posted a question about a tube that I had seen at the
bottom of telegraph posts. I realied they were on new posts.

I found out today that the tube is to allow BT to put a probe down to
ensure that the contractors had made the hole to the correct depth and
hadn't trimmed a bit off the bottom of the post if boring the hole was
difficult.

some of the smaller BBC tv relay station use "stout wooden poles" rather
than the better known lattice masts. One of these in the west of Scotland
blew over the the first winter gales because the contractor had met hard
rock after about a foot down and chopped off the bottom 4ft so it was only
held in place by the peat. (Fiunary. if anybody cares)
