My station in Berlin is very simple and unfortunately, I do not have any permanent antennas. As anyone living in a city, I am plagued by high levels of QRM on all bands.
For 160 through 10 meter bands, I use a ~10 meter long wire on a fiberglass pole on the balcony, matched with a CG-3000 antenna tuner at the feedpoint.
For 6 meters, I occassionally put up a horizontal dipole.
On 2 meters I use either a Diamond X30 or Arrow 3 element Yagi.
For QO-100, I use a 19dBi WiFi panel antenna on transmit and a 30 cm camping dish for reception.
