And then came the active devices for industrial salt mines and such.
Now they are marketing active corrosion prevention devices for cars. I saw
one the other day names 'CounterAct' or something like that. Not cheap.
$300 or so. It puts a charge on the body of the car.
So, anyone know of these things and how they might interact or interfere
with HAM equipment installed in a vehicle?

They place a relatively high DC voltage on sacrificial anodes located on
the car body. I would be suspicious of the claims by makers of such a
system.
No, that's the marine system, and the anodes are refereed to as the 'sinks'.
And I don't think these are generally powered at all.
These new systems are 'active' and do not have a sacrificial anode. They do
something with a charge, as you said, but I wonder how they would affect use
of ham gear.
As far as I can tell, these are not the 'snake oil' BS you usually see.
These are something that is derived as a 'consumer version' of industrial
devices that are used in corrosive environments, such as vehicles used in
salt mines.

I am familiar with sacrificial anodeshttp://www.ruststopnorthamerica.com/
cathodic-protection.htm as used in a marine environment.
An active system will not work without a conductive medium.
One of the systems touted for automobiles says it uses a combination of
active and sacrificial anodes... because an active system won't work
without an electrolyte.
