    I have an ATAS-120 I’m working to mount on a roof rack cross bar using an aerial mount made by the cross bar manufacturer. The mount has 180 degrees of rotation, which is the only way I can mount it on the roof. Otherwise, due to my parking requirements, I would have to mount low on a corner or bumper.

    In order to do that, I will need a support for the top when it’s folded down. A cradle with something to lock the antenna down. I’m thinking a mechanism on a mag mount base.

    Just curious if anyone has solved this sort of challenge or knows of resource(s) online where it’s been solved.

    No matter how you mount it, or how careful you are, sooner or later (usually sooner), you'll forget, and wham!

    The ATAS isn't a very efficient antenna to start with, so in reality it doesn't matter if it is mounted low, as that doesn't change the low Q of the coil.

    Valid points. Thanks for the insight.
