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 aspects here: Mechanical

This 3 elements is the First in a long serie of F-yagi’s. It has a boom diameter of 50mm. The element diameter starts at 25mm.
With a boom length of only 1,9 meters, this antenna performance equal or better compared to the competition with boom lengths upto 3..4 meters. Almost a full dB more compared to a moxon with only 0,3 meter more boom length.

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)

As with all HPSD antennas: each antenna is hand made and fully tested !
You will receive a handmade quality product!
And not just another antenna of the “line”.
