DCAN 14: Siting and Design of Radio Telecommunication Equipment
Minimising Contrast

3.2 The fundamental principle in siting and designing equipment is to minimise the contrast between the equipment and its surroundings. There are two components to this:
  • minimising contrast between equipment and people’s expectations of a particular scene - for example dark green antennas on a wooden pole at the edge of a rural road are most likely to fit expectations about rural landscapes.
  • minimising contrast between equipment and its immediate setting or background - for example fitting antennas to a floodlighting column or painting antennas to match the façade of a building.
3.3 The visual impact of equipment depends on how it is seen, both in terms of the image it conveys and its composition. In order to minimise contrast operators should where possible:
  • select a shape and material appropriate to the character of the area;
  • keep the shape simple with clean lines, and fit all the elements, such as antennas, cables and ladders within the visual envelope of the basic shape;
  • seek to develop a composition where the properties seem in proportion and balanced, for example masts that taper to the top are usually more acceptable;
  • minimise the number of separate visual elements in a base station; and
  • use regularity, order and symmetry in positioning equipment.
