Gaining some elevation for VHF operating is always a good idea. Most of the time, we think about this in terms of operating from summits or towers. Another option is to go up in an aircraft…and maybe jump out of it. Carlos/KD9OLN did just that with a parachute mobile operation captured on video.
In the video, the first altitude he mentions is 9000 feet, while over Illinois, which is about 800 feet above average sea level. That’s what we call Height Above Average Terrain.
