Gonna double check and #asknostr before I buy it, since I’m a complete beginner here... Is the low-900MHz range correct for an antenna in USA?

Also… how common are these in the northeastern US? If I want to actually be able to use it, should I build two and leave one with a friend or coworker or something?
