**4xYagis
vertically stacked**

**This group is
a very good configuration for contests: Good horizontal angle of radiation
and extermly low vertical elevation angle. Used by several contest-groups
in Germany! The stacking distance between all Yagis is 3,00m, not easy to
handle!**

**You can stack the 4 Yagis
with a harness of coax-cables (75 Ohm). Here is the method of
quarterwave-transformers used, too.**

**4x
lambda 5/4 or 7/4*V (l1) to the points X, then with further pieces of
lambda 5/4 or 7/4 * V (l2) to the point Y with 50Ohm.**
