433MHz Spring Coil Antenna with High Gain (3 dBi)

Antenna introduction:

This spring coil antenna matches great with any of our 433MHz RF Modules. It is a compact antenna, with 20.5mm length, and has 3dBi of gain and 50Ω impedance, so it will work fantastically with just about any 433MHz RF receiver / RF transmitter. The structure of this spring antenna is simple, lightweight, and it is made of copper-clad wire, so you can solder it easily.

Though this T15 Spring Antenna is in the 433MHz frequency band, we also have other 315/470/868/915/824-960/1710-1990MHz spring antennas, please contact us for more details, if you need to do any customization. Welcome to inquire!
