Active Loops are used with Active Tags. An active loop has receiver and no transmitter – the tag being powered up by its internal battery.

The standard loop gives an effective coverage of 8 metres. Customised shorter loops are available.

Active Loops can be placed directly onto the ground, but you must be able to hold the loop to the ground so that the Loop does not lose its form or move as athletes/bikes/vehicles pass over the loop.
For Motor Cross or another in-ground situation the Loop can be housed in a 50mm conduit under the track surface with the conduit on a slight angle to let any water escape.

When laying loops out, the loop width shall be 800mm (80cm).

When using 2 or more active loops you MUST have a minimum of 800mm (80cm) between the edges of the two loops. It is recommended that 2 loops be used in series at each timing point.

Each loop is connected to the loop controller with a hirschmann connector. There are 2 different types of connectors on each loop controller.
