2.Installation of Scanner Unit > 2.4 PRECAUTIONS
2) Preventing the connecting portion from becoming detached due to vibration
•
Keep the connecting portion between the coaxial cable and the flexible wave guide
and the scanner's chassis, and provide supporting members, as shown in Fig 2-11
Position of S-band supporting member and Fig 2-12 Position of X-band
supporting member, to prevent the connecting portion from becoming detached
due to vibration.
•
The distance from the connecting portion and the supporting member should be 400
millimeters for the S-band and 300 millimeters for X-band.
•
If the distance from the connecting portion and the supporting member is longer than
the above distance, vibration may cause metal fatigue, resulting in the occurrence of
malfunction even if the connecting portion is not removed.

member
•
For the cable end processing, refer to the procedure manual which comes
with the cable.
3) Permissible bending radius
•
The permissible bending radius R of flexible wave guide is 200mm/400mm
(E-bent/H-bent). More sharp bending with less radius than this must be avoided.
•
The permissible bending radius R of coaxial cable is 350mm. More sharp
bending with less radius than this must be avoided.
