[Elecraft] OT: Sloper Dipole Question

[Stuart Rohre]

Although it will not make a huge difference, consider that the lower portion
of a sloper has more capacitance to earth, thus, it is logical that it be
attached to the shield which is the ground side of direct coax feed.  The
higher upper wire would then attach to coax center conductor.  However, if
the sloper is truly a near balanced antenna; you would be using a 1:1 balun
or cable choke at the feed point, and then the coax sense of connection
would not matter if the choke or balun truly isolated the feedpoint.
However, it won't at all bands, and the lower part of a sloper is still more
coupled to earth.

Now some slopers work against a mast or tower conductor, and those are often
end fed at the tower, with the tower being quarter wave of the antenna, and
the sloper the other quarter wave.

I make the assumption you are talking about a half wave sloper, center fed
in my first comments.
