RF MARKERS
RF MARKERS
RF markers are used to identify buried utilities and are generally located, at regular intervals, directly on top of the utility they are marking.
The markers are passive devices which resonate at a specific frequency when energised by the marker locator. Each utility is identified by a specific frequency and colour.
In areas where optic fibre cables have not been laid in conduits with existing communication lines, RF markers are laid in the trench to plot the course of the cable. Our specialised locators enable us to determine the location of these markers to identify the location of the optic fibre cable.
