In this video, I take the ATU-100 antenna tuner on a portable ham radio adventure to a mountain summit (Summits on the Air), testing its performance in the field. As an essential piece of equipment for any ham radio operator, the ATU-100 is designed to match the impedance of the antenna to the radio, ensuring maximum power transfer and reducing interference. Throughout the video, I showcase the versatility and convenience of the ATU-100 as I use it to tune my antenna on the fly, allowing me to communicate with other ham radio enthusiasts from the summit. Join me on this exciting outdoor excursion as I put the ATU-100 to the test and demonstrate its capabilities in real-world conditions. Location is Apache Butte W7A/MN-095 on 4 March 2023
