See under "Kurzwellen-Faltdipol", 6190 kHz - Well, look here:
The line "Kurzwellen-Faltdipol" shows the 6190 kHz facility. The shabby
shack is the transmitter building, a provisional one from the earliest
RIAS days. If I recall correct (it's 15 years since I was there) the
vertically mounted fluorescent lamp behind one of the windows is in the
very room of the shortwave transmitter. Otherwise there is only an ancient
FM transmitter in this shack, if I recall correct.
The other transmitters are in what the webpage calls "Hauptgebaeude". The
antenna of the broken S4001 transmitter is the one labelled as
"Kurzwellen-Antenne noerdl. des Hauptgebaeudes". I understand that each
antenna is "hard-wired" to the related antenna, i.e. a swap is not
possible. Originally cover has been provided by the complete 20 kW
transmitter/antenna combination. When the separate 6190 kHz service
started in 1999 the concept changed in as far as transmission breaks
during maintenance or equipment failures are just accepted now.
"Teil des demontierten Kreuzdipols" was a vertical incidence antenna with
circular polarization for nighttime service on 990 kHz, now dismantled. At
some point in the nineties further use of this antenna has been banned,
because it produced too high fieldstrengths in the neighbourhood of the
station. Since then mediumwave transmissions are limited to the two guyed
masts, one of them carrying the 89.6 MHz antenna, too (the second RIAS FM
frequency, 94.3 MHz, has meanwhile been moved to the TV tower).
And a word about the transmitters: The remaining shortwave transmitter,
the one in the shack, is rated at 20 kW and has been delivered by
Telefunken in 1950, it is by far the oldest broadcasting transmitter in
everyday use in Germany (and perhaps well beyond).
The newer shortwave transmitter is or was an S4001, different from the
ones used by Media Broadcast in as far as it got no SSB capability and has
not been equipped for automated fast tuning. This transmitter suffered a
failure of the transformer that produced the plate current in 2007, no
such transformer was in the Juelich spare sparts stock due to the design
variants (at least I understand this has indeed been checked) and a
