Loop interference

Interference from adjacent loops

Loops connected to different loop detectors must have a minimum distance of 2 meters from
each other and operate on different frequencies.

For loops connected to a double detector this minimum distance can be reduced. However, it
must be ensured that the two loops do not operate on the same frequency.
