I think worrying about that is putting the cart before the horse. I wouldn't be expecting any fabulous results from trying this.

I want to raise my OTA antenna, but our community has a non-OTARD-compliant rule I've been toying with challenging. While gearing up and reading old FCC rulings, I stumbled across the following link:
http://www.fcc.gov/Bureaus/International/Orders/1997/da971364.txt
It seems many years ago TerraStar came up with a C-band antenna design that used three 0.5 m dishes on a 1.6 m baseline. This struck me as a little odd, because the overall sensitivity would still be less than a single 1 m dish. Then I realized what they were probably doing was nulling out adjacent orbital positions.
It can't be that hard to do because they were planning to market this along with C-band program distribution and wanted OTARD blessings from the FCC. The latter didn't happen, but the concept might be useful for someone with enough gain on a mini-BUD, but with problems of interference from nearby satellites. Cutting coax cables to length might be good enough if one did the math right and could vary the gain of phase-locked LNBs. Just food for thought.
