I think length IS critical in the matter of Beverage antennas, and the old axiom of "...the longer, the better" may not especially hold true...
I am speaking from personal experience here. I have a 1,500-foot long Beverage (extended from an original length of some 500-feet), that runs north-south, & is terminated at the south end. My southern K9AY consistently out performs the Beverage, hands-down, when listening to South American stations. I am seriously contemplating trimming the 1,500' length back by two thirds...
Before doing so, however, there are a number of things that I need to experiment with, i.e. (A) taking the pre-selector OUT of line more, when listening on the Beverage (signals are much stronger with the wire than they are with the K9AY anyway), and, (B) doing side-by-side comparisons during the dead of winter, when the ground is frozen & conductivity of same changes (my Beverage traverses a very wet, boggy, almost marshy tract of land for over half its length, which can't be especially "good" for its performance).
If my experiences with the Beverage is the same in January as it is now, then I think I'll definitely trim it back...
