Loop installation for temporary tracks For RC Racing
If slots for the loop cannot be made in the track, the loop can be fitted overhead on a bridge. Do not make this bridge of any
type of metal or carbon fiber, this will weaken the signal severely.
1. Construct a bridge (wood, PVC) with max clearance 45cm (1.5ft) (lower is better). Do not make the bridge longer than
necessary. Make sure no cars can pass outside the bridge 8
2. Wires of the loop must be 45cm(1.5ft) apart and fixed underneath the bridge. Put the connection box on top of the bridge.
Solder all connections and insulate well.
Please keep in mind that since a bridge has a larger distance between detection loop and passing transponder, this results in
a weaker signal for the decoder.
At dawn and at night, the interference from short-wave radio signals intensifies strongly and may occasionally cause the
transponder signals to get overwhelmed by the interference. To avoid this, keep the loop on the bridge as short (less than
3m (10ft)) and low as possible (less than 45cm (1.5ft)
Solder the loop wire end
