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.

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.
