I find most of these too long -- my installations at 30" high over flat 
midwest farmland would have excessive rear lobes if I followed those 
recommendations.

310-330 ft. and 520-550 ft. work well. F/B on my longer Beverages is 
sensitive to termination, but 810 ft. and 1080 ft. seem to be the best 
lengths. (I use too-short ground rods since all my Beverages are seasonal.)

Like SWR, F/B is never the whole story anyway. At my QTH, I need 
front-to-side with acceptable rearward rejection. F/S depends simply on 
length, and best "overall rearward rejection" rarely corresponds to best F/B 
in line with the wire.
