Grimeton VLF transmitter near Varberg, Sweden
The picture shows a commercial umbrella-antenna,
also called top-loaded monopole antenna,
build for a frequency in the 12 kHz range
for the former Omega Navigation system.
According to Klawitter and Herold,
those antennas had 16 top-load and 16 buried radials.
The 425m (!) high tower would roughly compare
to a 42m high umbrella-antenna for 136 kHz.
