My last presentation is available at www.wwrof.org webinar archive. http://wwrof.org/category/webinar-archive/ One single horizontal loop can make a difference between QSO and no QSO in all bands. Even a not well implemented loop like the one below. https://www.youtube.com/watch?v=GRZyKrsF1CQ For 160m you need the horizontal loop high as possible, more information on my Webnair, the slides are also available here. http://wwrof.org/wp-content/uploads/2016/03/WWROF-WEBNAIR-RX-Antennas-for-a- Small-Lot-.pdf I'm in a city lot, suburb of Ft Lauderdale Fl, VK0EK. 3D0A, C92, VP8's FT4JA, and almost every active station on 160m are in my log, over 300 countries heard on 160m and #286 worked since 2006, and HWF since 2010. Vertical polarization is not a solution for urban 160m stations to fight man made noise.
