After loosening the hex nut, connect the earth-bonding cable between the two
washers as illustrated in the figures above. Then, fasten all parts again with the hex
nut.
3.3.
CONNECTION OF THE ANTENNA CABLES
The Remote Unit has 7/16-type antenna connectors. Please refer to section
for its location. Refer to the corresponding documentation of the
connector manufacturer for mounting the cable connectors.
For the selection of cable and antenna it should be considered that, on the one hand,
a cable with higher loss is less expensive but, on the other hand, it impairs
performance.
Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft
lb) of 7-16 DIN connectors with 1-1/4 in opening to tighten the 7/16-type
antenna connectors. For example, use torque wrench of item no. 244377
available from the Andrew e-catalog. Do NOT use your hands or any
other tool (e.g. a pair of pliers)! This might cause damage to the
connector and lead to a malfunction of the Remote Unit.
