I've now built 2 different styles of astroplane as well as owning an original. The 2 I've built are different in design however neither have hats. Both have flat swr readings. Bother are now sitting 9ft between the ground and the hoop. One has a small hoop with the radials straight up to the cross bracket. The other has a 30in hoop and the offset radials like factory. So far 9ft off the ground I've had good results with a difference of 1 to 2 s units from other stations that I talk to daily.
According to what I've read the hat changes electrical length and the radiation focal point. Does it make a difference in function if you eliminate the hat and make the element longer? What about the size of the hoop? I've read that controls the toa.
Think think think. So many opinions.
I have no analyzer but one should be here within the next 2 weeks.
