Drone transmitters are available in different frequency bands. However, the 2.4GHz band is the most common for drone transmitters. In ideal conditions, which means you have a clear sight of your drone, a 2.4GHz transmitter can give you a control range of about 2600 feet. However, even though you may have the ideal conditions, other factors such as the antenna height and the receiver's sensitivity may reduce the signal quality and shorten the control range.
