Just a thought ... I have lost my copy of Orr's Quad Antenna Book ... but I
remember while researching a 3-4 element quad design .. I found that after the
basic Quad driven and the Quad reflector ... Giving u the ususal quad vs yagi
bennys .. when u added the directors .. the 1st dir (quad) gave u slightly less
gain than if the dir was a yagi element. As I remember it it was only a .2 or
.3db loss with the quad element ..and this trend continued as directors were
added. But if u plan to add the 4 directors for the 6 element configuration
... this cud possiably end up being a full db or so of gain if all yagi
directors were used... u might consider modeling a quagi ... seems it might b
a bit less cumbersom physically and result in as gud or better foward gain and
perhaps f/b as well.
I'm not blessed with the ability to model antennas ... but sure wud like to
hear the results of the comparison between the 6 ele quad vs the 6 ele quagi.
Gain / Take off angles / f/b.
