be In stations 1B9 29 laA9 8F9 12A9 16A9 and 20 C9 antennas on one side of the
building will be mounted on the building frame and on the other side on an
independent frame, If the protective angle is less than 69 degrees; if
the protective angle is between 69 and 90 degrees antenna mountings will
be on the building frames,
7o In all cases where independent antenna frames will be required later9 the
foundations will be constructed with the proposed system,
8e The following sketch shows the installation plan for the batteriesq
Batteries are not needed for Peipinga 17A9 and 25Fo Akkumulatorm
batteries: will be used9 with 110 cells for 220 volts/288 amplituden
(German)o In height the batteries will be at least 2020 meterso They
will be installed on the ground floor of the buildingso
