Hand made antenna with linear polarization, excellent tuned for 2,4GHz. 
You can  choose any frequency, just let me know when will buy. By default will ship antenna 2400MHz.
 
This is an excellent replacement for regular chines antennas for micro recievers.
Every my antenna tuned individually, it has photo with own chart VSWR and own serial number. You can see really VSWR and resonant frequency by marker on chart.
