I do it outside because I want my phone to get line of site radio communication with the satellites.
Fun Fact: you can contact astronauts on the ISS with 3 watts of rms power on a handheld when they are over head. 😁
Also, if you want to talk me with audio, I have been known to monitor 27.32500 megahertz on double side band amplitude modulation from time to time. I may or may not be able to get out with 500 watts. Heck of a time when the sunspots are in line.
Sorry, its Friday and I'm on a rabbit trail.
