Manual available on the Palstar website. Power switch label is somewhat confusing, as it is not on/off type - requires you to hold the button for a few seconds to power on/off. I tested and it works with the antennas that I tested (10m whip, G5RV, longwire). The item "Palstar zm-30 HF digital antenna analyzer ham amateur radio" is in sale since Monday, December 30, 2019.
