4.7 Installing the clamp fixture

Depending on the operating conditions, oscillations may be induced in the
antenna ring. This effect depends on
 the speed
 the antenna diameter (depends in turn on the measuring range)
 the design of the machine base
To avoid vibrations, a clamp fixture with extension is enclosed with the torque
flange enabling the antenna ring to be supported.

Mounting sequence
1. Loosen and remove the upper antenna segment screw fitting.
2. Screw the clamp fixture to the extension as shown in Fig. 4.7.
3. Fasten the clamp fixture and extension with the enclosed screw fitting to
the antenna segment as shown in Fig. 4.7. It is essential to use the new
fan‐type lock washers!
4. Clamp a suitable support element (we recommend a threaded rod  36
mm) between the upper and lower parts of the clamp fixture and tighten
the clamping screws.
