Review on π‘ DAOKI 10pcs 433MHz Antenna Helical Spiral Spring Remote Control Kit for Arduino Raspberry Pi - 5mm Compatibility and Enhanced Signal Range by Los Bizness
Worked well on a 433MHz transmitter module
Worked well on a 433MHz transmitter module, but hardly on a 433MHz receiver module (a few feet at best). Attaching a short wire (about 6 inches) to the tip of the helix on the receiver greatly increased the range.
- Input Impedance (Ohms): 50
- Type 90
