6.1.3 Strain Relief for Fibre Optic Cables
Figure 6-3: Fibre optic cables can be broken or damaged if care is not taken. The most common breakage point is right at the
connectors when the cables are snagged or pulled hard. Protect the fibre optic cables by making a strain relief. Take an extra loop
of cable and tape it to the handle. That way, if the cable gets pulled, the strain is taken up by the tape and not the cable.
6.1.4 Maintaining Proper Antenna Separation
Figure 6-4: When using the adjustable handles, the antenna separation can be maintained by using a length of rope tied between
the antennas.
