I can't speak to switchable bi-directional arrays but I can speak to my
900ft terminated beverage (450 Ohm resistor to a ground rod with 2 - 1 / 4
wave radials per band).  It has 20db plus front to back ratio on 40 - 160M.
The gain is sometime not much more than half an S unit to one S unit vs my
bi-directional 600 ft beverage (un-terminated), but the front to back
comparison is literally shocking sometimes.
