The picture shows the two Yagis mounted on a fishing rod for portable use in JO41WE, Hoher Mei▀ner, 720m high.

For stacking the Yagis must have other lengths for the elements! The impedance is influenced by the stacking, therefore new lengths are to be calculated. The stacking distance is exactly 1,30 m for a good matching with the given dimensions.

The stacked array 2 over 2 has a gain of 7,8 dBd including the stacking losses.

The stacking cable is 2x 3/4-lambda RG59 (2x 1,00 m)
