Personally I would not remove my installed local (crank up) antenna. If by
(and it will happen) some unforeseen chance you are parked under trees or do not have a good clear view of the south east sky, you may not get a signal. I have a portable satellite antenna and sometimes I have had a problem with getting a signal because of trees (located in a valley).
Purchase one of the new auto antennas that can be mounted on your access ladder on the rear, it is dome shaped, automatic and can be removed, placed on the ground to get a clear signal if need to be.
You may need to use your antenna (crank-up) to get local channels for local weather, news or programming.
