Even after that, it may or may not work depending on the remote model and the TV you have. Often, that range is limited by the minimum SNR (Signal-to-Noise) that the receiver needs to operate successfully. I am sending a packet of 4 byte every 2 seconds. They are also used in large number of consumer electronics products. The purpose of the capacitors is to shunt that RF to ground as close to its source (i.e, the motor) as possible. 8 ways to increase your drone's range phantomangel.rocks . Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna. In turn, the increased current shortens the battery life or increases the remote package size with a larger battery. Then locate the antenna(it looks like a small silver box). However, the -700s have an internal antenna so there isn't much you can do with them to improve the range. Thank you.
