Review on π‘ DAOKI 10pcs 433MHz Antenna Helical Spiral Spring Remote Control Kit for Arduino Raspberry Pi - 5mm Compatibility and Enhanced Signal Range by Douglas Holla
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.
- Frequency range (MHz): 433MHz +/- 6MHz
- Weak rate
