I don't understand why Beverage at first place, A rotatable Vertical WF can perform 11.5 db RDF on 160-80-60 and 40m rotatable on any direction and it take only 50ft maximum.
If you want high performance, you can build 4 delta flags in phase QDFA (0,180,180,0 degree) , enjoy 14 db RDF, 160 to 40m and needs only 150 ft long. This antenna could be reversable. I will make a commercial version next spring. You need a football field to phase 2 long beverage to get near 13 db RDF, and only works good for 160m.
The HWF is another level of antenna. I am at #299 now, but heard 315 countries on 160m since 2006.

Subject: Topband: Which compromise receiving antenna
I've just spent a very educational hour with Google Earth looking at my Beverage options for 160M. On a 45/225 azimuth I can only get about 215 feet. Is that even worth doing with a conventional Beverage? What about a BOG? Because of my lot layout I will need to use a reversible 2-wire Beverage with the NE end right outside my shack. Don't know if the KD9SV reversing transformers will work for a BOG.
My other reasonable receiving option is a K9AY loop or similar.
Transmitting antenna will be an inverted L, with vertical section probably no more than 60 feet. I'd like to finish my 160M DXCC this winter if possible
