7.4.7 Mounting of Antenna Beams
Put antenna beams into receptacles of the antenna head,
until the fitting is resting fully in the groove of the drilling
(see Fig. 104). Fully tighten by hand the compressing nut
until feeling distinct resistance. Tighten nuts by using a
wrench (10 mm), with a torque not exceeding 3 Nm.
Don´t bend antenna beams in order to avoid bearing
errors.
