Hi, Phil!=20

Have you considered a simple set of three paralleled half-wave dipoles =
hung
on the same 50 ohm coaxial feed line?=20

They are tough to get a really low SWR with, but just cutting the =
dipoles to
"formula length" usually produces something less than an SWR of 3 or =
4:1, so
the coax losses aren't high and the impedance should be in easy range =
for
the KX1 ATU.=20

And, being on one 'edge' of your property, it really doesn't hurt much =
to
have the legs of the dipole at right angles to each other or even to =
zig-zag
one leg a bit to fit where it can.=20

...So I'd like to put up another (not too ambitious!) dedicated antenna =
for=20
use with my KX1.  Criteria are:

o Coax fed: I have a coax line from the front porch thru the window sill =

now, and must route it around a doorway, etc. -- so ladderline is not an =

attractive option.

o Loadable with the KX1's ATU on 40-30-20 (this may be the tricky part).
