And what exacly would you want to patch there?
Bonded devices are connected to the same antenna cable, and on one cable you
can only convey one polarization (H or V) and one frequency band (high or low)
at the same time. So the restriction to same polarisation and frequency range
is necessary for device bonding, and I don't see how using a motor dish would
make any difference there.
