ZM-2 Antenna Tuner (like new)
- User Manual
ZM-2 with BNC -built and tested
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.
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.
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!
The ZM-2 will tune all bands from 80 to 10 meters
