Topband: Vertical with elevated transmission line?

[Richard (Rick) Karlquist]

FWIW, this is what I do.  I have 450 ohm line 5 feet high
over a mesh ground screen.  There is a balun at the end of
the line and coax drops down onto the mesh for the final
few feet to the feed point.  Seems to work fine.
