Sloping the ends of a beverage serves no useful purpose. That's an old wives'
tale (or maybe I should say old Hammy Hambone's tale) started by W1WCR, I
believe. Whether the wire is horizontal all the way to eacd end with a
vertical lead straight down to the ground point, or 50' of sloping the wire at
each end, you have exactly the same vertical and horizontal component of wire.
Precisely why a Pennant antenna and a Flag antenna of the same total height and
length perform approximately the same. The only advantage to the sloping wire
is that the sloping antenna itself acts as a guy wire for the end poles,
eliminating the need to terminate each end of the antenna with a separate guy
wire. But the long gradual slope makes the antenna wire more hazardous to
surface traffic than a short guy wire at each pole.
