Hi everybody my name is Robert and I am not new to the RC world. I have 4 plans, the Traxxas VXL 4x4, a boat, so I’ve been into the hobby for quite a while.” Actually since I was really young..!” And now I’m into the drone world so I bought the new A2S and i live in the city itself, (Chicago)..! My question is..? I need help with witch are the better, or best, signal booster’s that can go lower than 2.4 MHZ and with higher Db ranges…?”  The more options the better.! Thanks for ur time, I really appreciate it..”

You really shouldn't need any additional booster the DJI drones have plenty of range to maintain VLOS.

VLOS = Visual Line of Sight.

Okay I wasn’t sure lol. Well I’m flying beyond my (VLOS) and I live inside, inside the city. I’m only 15-20 mins away  from downtown Chicago so I’m in a really developed, and well populated area.
