[Elecraft] KX3 Antenna

I've used the MFJ telescoping whips successfully with my KX1 on 20M and
40M.  Of course, they don't perform as well as a good random wire slung
over a tree with a counterpoise (using a BNC to 2-terminal adapter), but
that option doesn't work when there are no trees available . or if
you're in a hotel room with sealed windows.  I've had good QSOs, indoors
as well as outdoors, with a whip mounted directly to the KX1 with a
right-angle BNC adapter, and a counterpoise attached to the bottom
thumbscrew.   And it became more versatile and less cumbersome when I
made a base for the telescoping whips, which is just a female BNC with a
run of RG174 mounted on an aluminum plate that also has a few
thumbscrews for attaching radials.   The base mounted whips work well
when there are no trees available . and even inside Hotel rooms.

The MFJ whips, when attached to my homemade base, test out well with an
SWR analyzer.  The resonant points are around 1.2:1.   So I plan to use
the same antennas with my KX3 if it ever arrives!

That's a Maldol 20-meter base-loaded 4' whip. No longer available, but  
this is similar:
