I am aware, I was asking just out of curiosity
With boosted antennas, you should fairly see and notice a good distance and better video reception. There are good and bad china knockoffs, so do your homework before buying. The most common are the parabolic, next are the advance are the FPVLR antenna, costly and dependable, I myself am a FPVLR user.
Here in the states, there are no FCC police. SARS, construction, and first responders uses boosted antenna in areas where reception are low in signal strength, with lots of obstructions or high geomag interference. This will give the pilot an advantage, but do not alter/mod your drone(s) inboard antenna system.
Good luck, and take lots of footage, and have fun here in the states, and if by chance that you cannot find an antenna of your liking, my best advice if flying here and unsure about the regulations, ask a LEO if you see one, Ranger, or the locals with a friendly smile. I find this is better than a boosted antenna.
Again, have fun and welcome in America in advance.
