ZM-2 ATU (Antenna Tuning Unit) - Order
The ZM-2 is a state of the art Antenna Tuning Unit. It is not just another standard tuner circuit repackaged. The ZM-2 has no inductance switching to mess with, just two variable capacitors to tune. And most times that is 1 to 1 SWR where other tuners only get close.
Just What Will It Tune? 
The ZM-2 tunes wire antennas: Random, Long, Short, "that's all I had"... It tunes BALANCED fed antennas such as Loops, Deltas, Dipoles, Verticals, V's! From field reports it has tuned: House Gutters, Window Frames, Swing Sets, Bedsprings, etc. It tunes out mismatch in COAX fed antennas to make the radio happy.Is It An AutoTuner? No, the ZM-2 is not an autotuner. But it still tunes fast! Approximate tune time on a strange new antenna is less than a minute! What Bands Will It Tune? The ZM-2 will tune all bands from 80 to 10 meters. Is It Hard To Build? An evening project for many, maybe two evenings for others. Easy pictorial assembly instructions.  There are build photos lower on this page as well as in the gallery.There is one large toroid to wind, and one small one to wind, but they are probably some of the easiest ones you'll ever do.
