📡 DAOKI 10pcs 433MHz Antenna Helical Spiral Spring Remote Control Kit for Arduino Raspberry Pi - 5mm Compatibility and Enhanced Signal Range Review

Wanted to make an antenna for a project I was working on but decided to order this. Worked great and now I have a few for future endeavors.

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.

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.

These little bugs, although not designed to work together, were arranged in a star pattern and soldered center and line to the weather station , for which it should receive data. I was working at 1000%, now I get all the sensor data with almost no lag. Excellent goods.
