This device is actually an "Un-un", as it has terminals for a wire, counterpoise, and co-ax.
By careful choice of core and windings, a 9:1 impedance transformation is achieved, enabling a single wire of appropriate length to act as an end-fed antenna. In my installation, a 44' piece of wire is usable on 40 and 17 Meters with no tuner at all. Most of the other HF bands are within range of a typical built-in tuner, including 80 meters. For a counterpoise, I used one 30' length of wire on the ground.
The results have been surprising. The performance is comparable to an endfed half-wave type of double the length. In field use, I have been able to make many qsos using a QRP rig of only 4W output. Signal levels are surprising.
This small, lightweight device is ideal for traveling, and also durable and weather sealed. Power rating is 150W, and I have used it with my FT-950 with no problem.
I rate this as an excellent value, and a very useful and clever device, particularly for portable operations.
