Mounting the ferrite core
The ferrite core supplied should be attached to the line cable in order to dampen radio cable
disturbances. The open ferrite core shown in the figure below is placed around the cable and
snapped together in order to close it. The neck of the core (see the U-shaped collar in the
figure below) enables the core to clamp onto the cable automatically, thus fixing it in position.

Figure 9-27
If the core does not sit securely in position on the cable (due to the cable having a small
diameter), a cable tie can be lashed tightly around the cable next to the closed ferrite core in
order to prevent the ferrite from moving along the cable.
