Hi

 

I wonder if anyone has modeled a owa antenna using the existing element
taper an diameters from? the Hygain series 105,155,205 antennas

 

I have several of these I would like to make them into owa design for the
bandwidth by eliminating the mast to element bracket ? insulating the
element? and inserting an appropriate size piece of tubing inplace of the
element to boom bracket an adjust the spacing ?? I do plan to update the
booms to 48ft an 3inch od for the 3 higher band antennas??? Has anyone every
considered this?? Im not real sure where to look on the net? There is not
much out there

Skip - I modeled a 44ft boom 8 el 10M yagi using the ARRL Yagi Design
software YW.  I bought a 105 and some additional boom tubing of 2.5 and 3
inch to extend the boom and used other Al I had to make the 3 additional
directors.  It has to be the most economical way to create an 8 el 44 ft
boom 10M yagi on the planet. And it rocks.  Its fixed on the tower to EU and
is about 2 S units stronger than my 4 el 10M beam doing A/B switching.  It's
a band opener to EU.
