Introduction: 5 8 GHz Double Helical Antenna

5.8 GHz Double Helical Antenna

In this video I will show you how to construct a double helical antenna for 5.8GHz. This design is useful in that it gives more db. Gain without sacrificing beamwidth. 3 turn = 9.5dbi 3 turn double = 11dbi 6 turn = 12.5 6 turn double = 13.8dbi 9 turn = 14.3 9 turn double = 15.5dbi Template: https://drive.google.com/file/d/0BzmJxxD-Z4B6TDJ4MDZUamNJRW8/view?usp=sharing

    very nice !!

    I will build it now

    thanks

    Do you happen to have the math behind the helix turn rate for the desired frequency?
