Antenna Design
For most of applications a 17cm piece of wire is quite adequate for 433 MHz modules. The range
achieved from the system is dependent on the choice and position of the antenna. The space around the
antenna is as important as the antenna itself. The optimum position is to locate the antenna so that is
protrudes directly out the top of the transmitter box. If this is not possible due to other design constraints,
try to keep the antenna, and in particular, the ‘HOT’ end away from other metal in the system such as
transformers, batteries and PCB tracks, especially ground planes.
