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.
