In this photo you'll observe 2 -2.4 GHz WiFi antenna. One from 3DR. 2 1/3" in length. The second antenna is from Cisco who makes WiFi products for the world. The Cisco antenna is quite a bit larger that the stock ones BUT THEY'RE
FOR THE SAME FREQUENCY RANGE. Can anyone tell me whats the difference ? I cant find any spec sheet on the 3DR antenna so i have no number to refer to as to ability to receive at what distance. the Cisco is rated at 5db. Whats the difference.?
thankx to all
