The mast of the radar antenna consists of aluminum tubing from 1o to 15

cin in diaraet3r,? The mast can be dismantled into three components and has
a hei3ht of about 8 mote-s., It was mounted on an iron pedestal weighirg
about 150 ib, It was braced eight tines and the wire ropes were insulated
with egg--'shaj ed porcelain insulatorsCThe top of the 'scat mounted the .
reducing gear which consisted of a fixed and a rotating unit
This reduci

gear which was about 1 motor high comprised the antenna motor, the high
frequency voltage pick-up, and the rotating recorder (Drehmeldesystem).
The antenna proper is a neven?element yazi.type antenna, four-fold, in
two..planes, Its noaaureMEnt.s were about 3 x 4 x 4 meters. The dipoles
were about 130 cm long aid had a thickness of abuu. 1.5 do. FA" antemm
unit had five directors and one reflector.. The antenna was capable bf
gullrotations as well as of swim? ing- motions within epeoif is sectors.
The rotating recording system consisted of the recorder located in the
reducing ;ear, and the receiver located in the panoramic view set and in
the azimuth set. The trar..smission of the values determined was effected
through a muJ.ti-oore cable exteiidivg from the recorder to the reoeiviere
