Emtech ZM-2 Antenna Tuner

Last Saturday I ordered a pre-built Emtech ZM-2 antenna tuner with UHF connectors and it arrived today.  I wanted something a bit smaller and lighter than my LDG YT-100 for use with my Yaesu FT-817ND. Additionally, I wanted a tuner that would work with either coax cable fed antennas, balanced line antennas, or even just a random length wire with a ground.

Unlike the LDG, the Emtech unit is a manual tuner using a Z-match circuit. However, based on several videos I've watched and reviews I've read, it's quick to tune and gives you a wide choice with antennas and feedlines. (See here for a good discussion of Z-match circuits.)

Weather permitting, I am hoping to try it out this coming weekend. In the interim, here's a good video from W2AEW on how to operate the ZM-2.
