868MHz T13 Spring Antenna with 2.5dBi High Gain
Antenna introduction:
This spring coil antenna matches great with any of our 868MHz RF Modules. It is a compact antenna, only 16mm long, and has 2.5dBi of gain and 50Ω impedance, so it will work fantastically with just about any 868MHz 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 T13 Spring Antenna is in the 868MHz frequency band, we also have other 315/433/470/868/915/824-960/1710-1990MHz spring antennas, please contact us for more details, if you need to do any customization. Welcome to inquire!
