Emoto has an obvious answer to the mast alignment problem: they make a
series of flexible couplings - these are two metal plates spaced a short
distance apart and use a system of pins and slots to transmit rotation
while tolerating small amounts of both lateral and axial misalingment.
The plates have the same hole pattern as their rotators and mast
clamps. They are standard equipment on their largest couple of units,
options for the rest.
With their 6-hole metric sizes, they aren't directly useful with
HyGain rotators, but they could be redrilled or imitated.
