After much advice here and thanks to a friend of a friend I took delivery of this today.

1.3 m high, many kilograms heavy!  It's been treated with zinc phosphate primer and will get a couple of coats of Hammerite or equivelant before planting.  This weekend I'm running Cat6 cable out to the plinth and starting to build the equipment box which will be fitted to the bottom of the mount.
