The Yagi-Uda antenna generalities
If a conductor of length equal to half a wave is placed near a dipole, the electromagnetic field radiated by the latter induces an HF current of the same frequency but of much less amplitude in the conductor
The clemens match
The Clemens match is easy to make and reliable, and is preferable to a single Gamma match as it is balanced
Two elements YAGI for field day operation
The antenna should cover 20m and possibly 40m band. The whole antenna kit should be light enough for hand carrying to most remote area
The Clemens Match,gamma Match
The Clemens match is easy to make and reliable, and is preferable to a single Gamma match as it is balanced
