** Free Shipping **

The Z-11ProII provides semi-automatic antenna tuning across the entire HF spectrum plus 6 meters, at power levels up to 125 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some other tuners you may have considered, including the built-in tuners on many radios.

The Z-11ProII is similar to previous LDG tuners, but is specially designed with battery powered operation in mind. It uses little power while tuning, and essentially zero power when in standby. Onboard solder pads allow easy connection of a user-supplied internal battery pack, for the ultimate in convenience and portability. The new Z-11ProII uses a lower battery voltage than previous versions of the Z-11Pro; this means fewer battery cells are required, making the Z11ProII even more lightweight than its predecessors.
