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 Types HPSD 6 Short.
The first
design is actually to short to be called a real 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 responsible for the
high FB & FS and wide SWR coverage. Due to the high FB/ FS and wide
SWR this antenna is ideal for stacking.
