The North Auckland high-power wireless station: the steel mast reaches its full height of 400 feet

The mast weighed 60 tons (the weight is often quoted as 120 tons, which presumably includes the weight of rigging, the aerial and the downward tension they exert). The bottom of the tower came to a point and was ball-shaped so that it could pivot in a steel cup on top of a stack of glass insulators.

It appears workers are jacking up the tower in order to remove the timbers, on which the tower was built, before lowering the tower onto its glass insulators. The sign appears to read: "Viewers (Visitors?) are not allowed on the tower. By order".

One of three anchor blocks for the tower at Awanui wireless station. There were two sets of three solid steel guys: one attached to the tower at the 150ft level of the tower, and the other at 300ft. The top 100ft of the tower was self-supporting.

The umbrella type antenna extended 50m from the tower, and with its supporting wires covered a circle 360m in diameter. From original blueprints of Awarua/Awanui wireless stations. The fuzzy mark to the left of the tower is the crease from where the blueprint was folded. (Click for larger version)
