Folks - a lot of the 50+ year old mast bases, especially between Brentwood and Seven Kings, appear to have been fitted with Heath Robinson like jackets some 3ft high from the ground. They look to me like an ill-fitting sock! Anyone know what these are for? Is it to rigidify the masts and mask any corrosion where they enter their concrete "feet"? If so, what's the design life?

OLE? Object Linking and Embedding?
I've seen telecom masts with full metal jackets at the base that I always assumed were to deter casual climbing attempts.

OLE? Object Linking and Embedding? Overhead Line Equipment (more often OHLE, spelling Overhead as two words) |

These would not be tall enough to deter climbing; in fact anyone so stupid as to try could use them as a foothold, before getting fried....

The so called 6" masts were assessed as being inadequate in many situations. The usual mode of failure of masts is buckling at the bottom. To strengthen them one can add more steel to the lower third or so, or encase them in a reinforced concrete jacket.
The embedded masts can also suffer severe corrosion just above the concrete and these can be repaired in similar manner.
The design life for original and repaired OLE structures is 40 years (!)

some of those masts date from 1949 so we don't owe them anything!
