All I need is a more stable LNB, not one that is continually hopping about. A better TXCOI will be fine, the software does the rest.

you just need the two polarisations

for additional nb or wb receivers you can split these outputs in two or
4 port splitters

reference in?? if i modify lnb for external in its easy to add an sma socket ... but i mount a tcxo inside lnb

However, the extra cost is small, and having the extra feeds allows
you to check other signals while retaining operation on the signals
you want. Quad allows two polarisations, plus one test feed, plus one
frequency reference input co-ax.

Also allows for one to fail, although I'm unsure how likely that is to
happen.

It all depends what suits, of course.
