hope the attachment gets to you..
there are several types of parabolic , (I havent sent everything )
You could make a solid dish with a raydome cover ( you wont see the launcher, like like a drum)
a solid dish with a launcher (no raydome cover)
a grid pak dish with a launcher ( vertical polarisation and horizontal polarisation)
then there is the blue schematic with lightning strike..
would be great if you could adjust the X axis ( distance between dishes) without distortion to either dish , merely an elongation or contraction of the lightning stike. .. hope you understand
