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.

I was having an educational discussion with a friend tonight about the
ramifications of feeding a vertical with an elevated transmission line. The
situation would be he does not want to dig up the mesh for the 20' around the
base. It was suggested to bring the transmission line out of the ground about
8'
high to the tower and then down to the feed point. I wondered about it enough
to
ask here. I wasn't sure how to model it with eznec. Thanks.
