The setup is a little unusual: a satellite internet link (which
continues to work throughout the gusts, so dish pointing isn't the
issue), a DVB-S LNB offset by the appropriate amount so that it 'sees'
the Astra 2A-B-D satellites instead of the Europasat internet satellite
which the dish is aimed at,

Just a guess here, but if the dish itself isn't moving maybe the arm
holding the offset LNB is? Possibly it's giving corrupt data packets to
the receiver which doesn't like it?

Couple of our old Sky digital boxes locked up with a similarly noisy
input...

If it is a wind problem you can try moving the affected bit around by
hand and if you can repeat the problem then tighten up and realign as
required.

Also are there any trees overhanging the dishes even some metres away at
all, they can really clobber sat signals and even more so when wet...
