With a boom length in the order of 12 meters for sure, this is not a small gun!
On the mast as well as on the rotator a high amount of effort is asked.
For the mast you must think in the direction of construction mast (tripod/square), the rotator must be at least an equivalent of a G1000 for long lasting results.
But once past these obstacles a high quality DX station is born, Famous DXers like 13OT001, 47DX101 are always on top of those pile-ups

Conclusion: a 6 elements yagi placed high is a BIG GUN!

                                                                                      


Short version Boomlenght 7,3 meters Typs HPSD 6 Short.

 The first design is actually to short to be called a "rea"l 6 elements monobander.
You can think of the antenna as an optimized 5 elements. The additional element in front of the Radiating element (J), is responseble for the high FB & FS and wide SWR coverage.


Due to the high FB/ FS and wide SWR this antenna is ideal for stacking.
