Drop Cable Installation
Drop cable is provided in two types 6 Series and 11 Series (low loss). Use this procedure to
install the drop cable.
STEP PROCEDURE
1. The drop cable is normally provided with one end already terminated with an weather
proofed F-Type connector for use at the Outdoor Unit. The cable is manufactured in
three lengths (25, 50 and 75metres) and an appropriate length should be selected. In
some circumstances cable is provided on 300metre drums and both ends of the cable
are terminated during installation.
2. If the drop is not pre-terminated and requires an F type terminating at the outdoor unit
end. It is suggested that the F-Type connector is terminated to the free end of the
cable before running the cable. See Drop Cable Termination (6 series) or Drop Cable
Termination (11 series)
3. The cable is installed starting from the antenna end leaving the free end of the cable
to be finally dressed into place and cut to length for neat connection with the power
supply unit.
4. Run the drop cable from the outdoor unit end to the F-Type connector to the SIU.
5. The maximum drop cable distance between the SIU and the outdoor unit must not
exceed the length of the drop cable (50 or 75 metres).
6. The 6 series cable has a minimum bend radius of 70mm. The 11 series cable has a
minimum bend radius of 100 mm
7. Secure the drop cable to the antenna mounting bracket or pole using straps. Leave
sufficient slack to allow for antenna panning at the commissioning stage.
8. Secure along the drop with 7mm cleats as required. Ensure that a drip loop is formed
at the point where the cable enters the building to avoid the ingress of water into the
building.
9. Plug the F-Type connector into the connector on the rear plate of the outdoor unit.
Important Notice: Care should be taken when screwing the F-Type connector into the
connector on the rear plate of the outdoor unit to ensure that the connector is not
over-tightened as over-tightening will strip the thread. Use a torque spanner set to
2.3Nm. See figures below for pole mount and for wall mount installation.
10. a) Use rubber boot to provide environmental seal if provided as part of the
installation kit Push the rubber boot over the connector and ensure that it mates
properly with the raised plastic ring on the outdoor unit housing. Once the boot is in
place a tie wrap should be placed around the cable behind the boot to ensure that the
boot does no become displaced.
or
b) Wrap self amalgamating tape over the joint of the mated connector. When using
self amalgamating tape, strip back the interleaving and stretch the tape by between
one third and one half. Keep the tape under tension and wrap, overlapping successive
layers by 50% until the desired build up of insulation is achieved. Finish the wrapping
by holding the tape under the thumb and snap by stretching. The high degree of
stretch as described above prevents the inclusion of voids and ensures rapid
amalgamation.
11. Run cable end up to the SIU. Estimate the length of end required for termination of
cable (allow 150mm of conductor for a maintenance re-termination of cable) and cut
cable to length.
12. Terminate the drop cable. For termination instructions see Drop Cable Termination (6
Series) or Drop Cable Termination (11 Series)
