(Note I.G.: According some my
information the 30- artillery division had four underground antennas.
There were “trenches” antennas similar to described in the above
post by Andrey 1967 (RA6AMP).
One antenna had direction of radiation to Moscow radio- center.
Second antenna had direction of radiation to Odessa radio- center.
Third and fourth antennas were intended for communication with
ships on the Black Sea. The two antennas had direction of radiation
directed to West and East of the Black Sea.
However a German artillery
shell destroyed the feeder shaft to the underground antennas making
those ones useless. It was 610-mm shell from mortar “Karl.” The
feeder shaft was close to the on- ground antennas and it was destroyed
at the same time when the on- ground antennas were smashed. ”
Figure 4 shows a shell from mortar
“Karl.” (Reference 4))
I have seen underground antennas in a radio communication
center in Saratov Region, Marx- district. The antennas were made
from a coaxial cable. The coaxial cable was lying on a gravel
“pillow”. Antennas were buried on to 1.5- meter in the ground.
Design of the underground antenna was similar to a logo- periodical
