The range of your RC vehicle could mean the difference between driving successfully around an obstacle and having an accident due to a loss in control. The connectivity of your transmitter and receiver depends on the length of your antenna; however, there are ways of altering the length without drastically reducing the efficiency of the systems functionality. Learning how to properly apply a base load to your antennae will offer you improved connectivity, while also reducing the length of your cumbersome antenna.
