Relevant rules in the Regulation:

  • Schedule 1, Part 1.4, Division 1.4.2, Section 1.53.

A mast antenna and support structure doesn't need DA approval if:

  • the antenna is a receiving antenna only, or an antenna that can send and receive a signal
  • its diameter is not wider than 0.75m
  • it's mounted on the ground, and the antenna is no higher than 6m above datum ground level, and
  • it's mounted on a building, and the antenna is no more than 1.5m above the highest point of the building. The antenna's colour must also match the colour of the building.

Mast antennas are class 10 buildings. Extra criteria apply if you build two exempt class 10 structures within 1.5m of a side or rear block boundary.
