I use 5 two wire Beverages for 10 directions and have good directivity down to the 175 KHz LF BCB and they are only 500-700' long. Performance seems to exceed published info. On the US BCB its like aiming a long yagi on 2M, multiple stations on the same frequency can be heard with ease during the day. It more jumbled at night
Sometimes I wonder if its my very poor RF ground conditions that tilt the wave more and result in the performance of a much longer antenna.

The A while back, I built a 4X2 low band array of receive verticals aimed at Europe via Canada, but reversible to beam over San Francisco. I could tune to 960 kHz and listen to a San Francisco station 70 miles away on ground wave with armchair copy or reverse the array and listen to a Canadian station also on 960 kHz again with armchair copy. The array seemed to be on a par with my NE beverage. BTW, my beverages are only 400 feet long but often work quite well on the broadcast band.
