3.3 Installation Schemes
The installation and placement of antennas and NS50 units will depend on the wireless coverage
type, rock type and tunnel topology. A few examples of installation schemes in a mine are described
and illustrated in the following sections.
3.3.1 Installation in a Straight Drive
An example of a straight drive installation scheme is shown in Figure 9: Installation scheme in a
straight drive.
Two Yagi antennas are clamped to a mounting pole, which is chemically adhered into the mine
roof.
The antennas are positioned in opposite directions to provide long range wireless coverage.
