2. Installation of the Detection loop

The AMB detection loop is made of a special water-resistant wire to guarantee durability

and has the resistor already installed. Keep the resistor opposite to the connection box

(the box that connects the coax cable to the loop).

Loops installed in re-enforced concrete may suffer from a noticeable loss of sensitivity

(less reach of the transponders) especially at wider tracks, since the steel underneath the

loop forms short-circuited loops. This weakens the signal from the loop. If unavoidable,

put the loop where the track is the least wide and put the loop wire in no deeper than

necessary.

Installing the loop:

The detection loop must be positioned in such a way that the transponder is in the

middle of the two loop wires when the front of the RC model car is above the finish

line. If there is a possibility of RC model cars running outside the track, you may need

to extend the loop, but at all times keep the loop within 10 m / 33ft maximum width.

Keep the extensions as short as possible.

Cut the slots in the track

maximum 2 cm / 3/4” deep

and

30 cm / 1 ft apart

, with a

suitable cutting disc/saw. To ensure one hundred percent detection, make sure RC

model cars can not pass outside the detection loop.

Put the wires of the detection loop in the slots and cut the excess length of the

detection loop wires.

Put the heat shrinkage sleeves over both of the detection loop wire ends.

Solder

the

wire ends to the short wires of the connection box. Put both the shrinkage sleeves over

the solder connections and shrink them by holding them over a heat source.

Fill the slot with silicon. Make sure the silicon is fully under the surface of the track,

otherwise the tires may pull out the silicone. For OFF-ROAD use cover the loop with

carpet or similar. The

carpet can be covered with sand.

The detection loop is sensitive to interference, possibly emitted by nearby cables. To

avoid possible interference keep all cables 3 m / 10 ft or more away.
