Material list for building a 4 Elements Yagi
To build the 4 Elements Yagi you may follow the direction for building the 3 Elements Yagi except that you will add an additional parasitic element (director) which is about 5% shorter than the last element of the 3 elements yagi. The spacing are the same between the elements and when built successfully it will give you a very desirable 9.39dBi gain or about or about 7.24dBd.
To increase the performance you may also configure the antenna in stack configuration by making two antenna’s and connect it with a phasing harness for increased performance.
