LW antenna Zehlendorf 177 kHz - antenna tuning elements
antenna tuning unit
"The inner life" of the antenna tuning hut
There are two rejection filters for 603 kHz and 693 kHz in the rear of the hut, because from a nearby MW antenna on the site these two frequencies are radiated simultaneously
Design of atu
with filters
for 603 kHz and 693 kHz
The rejection filter for 171 kHz consisting of C31 and L31 was installed in order to ground the cage antenna statically once more , although it is already statically grounded via the base grounded mast.
