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.

Difficult; I'd need to run a mains cable up to the roof then take a TV
up there to see what happened. I hope it doesn't come to that.

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...

As I've found, in a different place where a tenant has a dish on the
wall outside his flat. Fine in winter, variable in summer. I'm thinking
of putting a dish on the roof there, "God willlin', an' if the crick
don't rise", as the country-corny American saying has it.

But here the line to the Astra satellites is completely unobstructed
(the Eutelsat satellite is, luckily, sufficiently high to be 'visible'
above the neighbour's chimney pots).
