The F-yagi is the end result of combining all “positive” aspects from different yagi style antennas.
If you are a DXer and want maximum from a single antenna, the F-yagi is the way to go!  You can read all about the F-yagi here: F-yagi
Besides these positive electrical aspects, the F-yagi produced by HPSD is of outstanding mechanical quality. You can read all about the mechanical ascpects here: Mechanical

This 6 elements F-yagi has a 50mm boom (double wall thickness).The elements diameter start at 25mm.
All elements are isolated from the boom. This will ensure pattern stability after many years.
Of course a RF choke is provided with the antenna. (2Kw)
