Review on πŸ“‘ DAOKI 10pcs 433MHz Antenna Helical Spiral Spring Remote Control Kit for Arduino Raspberry Pi - 5mm Compatibility and Enhanced Signal Range by Douglas Holla

Revainrating 4 out of 5

Nice but not sure if it will work

I've read that 433MHz RF needs to be wrapped like this to optimize signal reception. I haven't noticed any signal gain when using them on the transmitter or receiver, but I think since this is the correct way to TX/RX it must be the modules.

Pros
  • Frequency range (MHz): 433MHz +/- 6MHz
Cons
  • Weak rate
