I believe it is the same manual as that for the A743. At least the  
A743 manual does have dimensions and directions for 30 meters.
I have not been able to make the A743 work very well with my A3 (not  
S) - I now think it is the dimensions of the director and reflector  
that are off. When Cushcraft went to the A3S, they slightly modified  
the element dimensions. The problem I see is that the antenna  
resonates below the 20 meter band, even with the elements shortened  
as far as they can go. Obviously something is off...
