I know many of you will say "1 mile? That's it???" - But for me, and my hilly somewhat-densely populated town this is a 100% increase over my flights before having the antennas installed. (I would loose video around 2000' out or so.) I only turned around because I was scared! (I still had full control & video) Remember... the rules say you need to be in LOS! I also exceeded the FAA 400' rule... Duh. Pay Attention!
