Aerial mast base

[Mike K]

Looking at the manuals , they refer to the vehicle mast D rods as being made from DURALIUM , but , the static 3 feet 7/8" D rods in the ground kits are steel , plated with a rust inhibiting coat of copper or similar . This makes sense as 7/8" steel rods would be too heavy on a mobile setup such as a carrier or armoured car , too much weight and stress on the base . I think DURALIUM is a form of aluminium ?

Any comments ?
