Stan,
It can be made to work, but will be a real "bear" to adjust to resonance
unless you separate the ends.
If you are feeding with 300 ohm twinlead, why not make a 66 foot long
center fed dipole out of it.
Alternately if this is for portable work, us no feedline at all - just a
BNC to binding post adapter at the KX3. A 58 foot wire connected to the
red post and supported by your crappie pole. Add a 16 foot "Radial" to
the black terminal and string it out on the ground. The KX3 ATU will
handle it on 40 through 10 meters.
73,

I found the plans (June 2010 Elecraft Reflector) to build a 40/30/20
meter "linear loaded" portable antenna for my KX1 (using a crappie rod,
300 ohm twinlead for the radiator, a BL2 balun, and ribbon cable radials
cut to 1/4 wavelength for each of the bands (16, 25 and 33 feet).
My question is how terrible would it be to use a piece of that thin
computer ribbon cable cut to the three lengths but NOT separated? This
would make it easier to deploy and roll back up.
Has anyone ever tried using unseparated ribbon cable counterpoises? The
materials are on order and I'm sort of anxious to know.
Obviously, this is a compromise antenna and I'm shooting to design a
package for maximum installation speed vs. maximum efficiency.
Thanks, Stan WB2LQF
