I'll have to ask a cable guy what they do, but all of the connectors
for the aluminum hardline I have seen are aluminum as are the housings
of the amplifiers, so the dissimilar metals issue does not exist 95%
of the time in the cable TV world.

In the RF world that is another story, I just took the silver plated
coupling loops out of a Sinclair aluminum cavity and it was covered in
a fine white powdery scale where the connector made contact with the
can which I am going to assume is Aluminum Oxide, don't really have
the resources to have it analyzed.
