supply.
Always use Cat5e cable that is gel-filled and shielded with copper-plated steel. Alternative
types of cable are not supported by Cambium.
The maximum permitted lengths of CAT5e cables are specified in

‘Main’ drop cable
: To prepare a long section of cable to connect the ODU to the LPU,
proceed as follows:
1
Cut off the approximate length required (allowing a bit of surplus), or leave it on the
drum so that it can be unwound as the cable is hoisted.
2
Slide one or more hoisting grips onto to the top end of the main drop cable:
To determine the number of hoisting grips required, consult the grip manufacturer.
3
Secure the hoisting grip to the cable using a special tool, as recommended by the
manufacturer.
4
Fit an RJ45 connector and gland to the top end only, as described in
