What if we went crazy and......

designed and fabricated a fiberglass 48" Cassegrain feed parabolic reflector and mounted an ASC421 grafted to a Universal Ku lnb (see attached image) at the focal point. It would be a challenge to arrange the feeds to clear the HH Motor wouldn't it.

Cassegrain Antennas
The cassegrain antenna is most often used for dishes that exceed five meters in diameter. Its use is primarily restricted to uplink earth stations and cable TV head ends. The cassegrain design incorporates a small sub reflector located at the front and center of the dish. The sub reflector deflects the microwaves back toward the center of the reflector, where the feedhorn is actually mounted.
Like the prime focus dish, the cassegrain antenna's view of the satellite is partially obscured, in this case by the sub reflector. However, when the diameter of the dish exceeds 5m, the percentage of blockage is actually quite small.
This type of antenna obtains higher efficiencies because the feedhorn looks up at the cold sky and the required illumination taper is reduced. The precise manufacturing tolerances required to implement this dual reflector approach, however, increases the manufacturing cost and adds complexity to the installation process.
