Thanks for the input. I live in the Boston MA area, and drive the highway
in and out of the city each day. I often park right along the ocean too,
and we're talking the frigid North Atlantic here! I've had times where it's
difficult to get into my vehicle from the ice that can build on it. I'm
concerned that the motor in the antenna might freeze up. Any thoughts on
that?

Apart from the obvious (and probably unhelpful) comment that you shouldn't
try to tune the ATAS120 while it is frozen, no sorry no thoughts.

Most of my mobile HFing is on 20m where I find that the ATAS120 seems to
have a wide enough bandwidth that I hardly ever need to retune unless
I change band away from 20m. So, it might still be practical if you
don't want to retune while conditions are cold enough that the motor
etc. might be frozen up. I've only been using mine about a month so I
have no idea what will happen in the winter months when it gets iced up.

Cheers,

Mark.
