Thanks for the interesting photos of your dish.
Bowties are full wave dipoles. Since they are a collinear pair of dipoles spaced very close together, they don't have a lot of gain over a halfwave dipole. I suggest you use a stacked pair of halfwave dipoles, one above the other, fed in phase, for smaller size and greater efficiency at the focal point. A vertical spacing of 5/8 wave at the design frequency would give max gain. Adding a reflector behind the dipoles would give additional gain.
