The OWA yagi style was invented by WA3FET. This type of antenna is already known for quite some years and still remains one of the best of its kind.
The OWA (aswell as the F-yagi) has a direct 50 ohms impedance.NO matching system is needed. This will reduce “loss”.
Beeing a 50 ohms direct feed antenna the antenna is less sensitve for rain/snow and nearby objects. (swr/gain-effect).
The best thing about the OWA is that it has a relative high values (gain/fb etc) which remain high over a wide frequency.

The OWA is the only antenna which has such high values over such a wide frequency range.
Besides these positive electrical aspects, the OWA produced by HPSD is of outstanding mechanical quality.

You can read all about the mechanical aspects here: Mechanical

IF YOU WANT A WIDE BAND ANTENNA WHICH CAN BE SET FOR 27 AND 28 MHZ, THIS IS IT.

The 5 elements is one of HPSD’s DX-guns. Small enough to compete with the really big guns and Big enough to be better then most.

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”.

 

 

 

Above the 5el OWA- Yagi freespace plot.

At 18 meters above average ground the gain produced under a 8 degree angle is 15,05 dBI

The 2 MHZ SWR bandwidth without matching is  impressive !
