I have a KX3 instead of a KX2, but I frequently go out in the field to play
radio at local parks and other scenic spots. I have a number of antennas,
but one of my favorites is one I built recently, a link dipole for 40, 30,
and 20. It's tuned for the CW portions of the bands, so it doesn't need
I'd like to suggest that one very good reason for using centre-fed and external
matching unit is because the harmonic pickup from nearby stations is much
reduced compared to multi-band antennas. This is best implemented when the
antenna is as near perfectly balanced as possible to avoid
The only issue I've encountered with single band antennas, to staff a
Field Day site to operate 2 or 3 stations per band, and 5 bands, there
needs to be some 10 to 15 antennas erected. Where as a single 135 ft

Absolutely. The other advantage of a horizontal dipole (or inverted V) is that
it will be far quieter than the wire.
An end fed non-resonant wire installed as a sort-of sloper “works” but is far
from optimum. Especially since you’re using a minimal counterpoise system.
One counterpoise wire
Shu,
If you add the 58.5 foot wire to the 16.5' counterpoise, you have a 75
foot antenna. That is close to a half wavelength on 40 meters. You are
feeding it off-center which will allow it to be used on several bands
(even though one of the antenna wires is on the ground).
As I recall,
If you are talking about a single band dipole then any half wave dipole cut
to the standard formula and fed with good quality coax should work well. If
you want a "multi band" dipole then I would recommend cutting it for the
lowest frequency you plan to operate and feeding it with balanced line.
Your field antenna is essentially a very low off-center fed sloped
dipole slightly longer than a half wavelength. I'm not surprised you
can tune it with the KX2, but it certainly isn't any kind of ideal
antenna configuration that Elecraft would design for. They just made a

I have had my KX2 with the ATU for about 10 months and operate on 40m QRP SSB
from various locations. Experimenting with different antennas I have
experienced best results with a 58.5’ wire tossed about 25’ up a tree with a
16.5’ counterpoise. I ran the same length wire from my house to the
