FIELD: mechanics. ^ SUBSTANCE: device includes mast, two clamps, which are elastic. Ends of clamps are rigidly fixed in pins the threaded ends of which are arranged in corresponding holes of presses plank. Two base planks have prismatic cutouts and connected to pressure plank and to each other by means of bolts. Pressure plank has twelve holes arranged in circumferential direction and representing the possibility of unrestricted axial movement with pitch of 30 degrees. It is attached to mast with clamps, and antenna element together with base planks is attached to pressure plank by means of bolts. ^ EFFECT: reduction of manufacturing complexity, improvement of convenience at device operation and enhancement of reliability due to replacement of design of base planks. ^ 4 dwg |
