Description

Description:

The 40m-10m UnUnTenna is a compact portable wire antenna for backyard or portable SOTA use.
It uses an integral 9:1 voltage balun that matches your unbalanced 50 ohm impedance input to a 450 ohm impedance unbalanced long wire.
The autotuners in the Elecraft KX-2, KX-3, IC-703, and our manual Multi Z Tuner have all been tested and work very well.
The antenna has optimum efficiency at 20m and will be an S unit less in performance at the 40m and 10m ends.
You use a non-resonate length of wire for the driven element, typically 41′, 35.5′, or 29′, and optionally a 1/4 λ wire for a counterpoise, 35′ length counterpoise works well for all bands.
