My CEL was caused by the O2 sensor failure. New sensor fixed that. Had to reset the CEL afterwards to get the light to go off.

Go to Auto Zone and have them read the codes(if any) for free. Give you an idea of what's going on. As for the antenna/radio, pull out the head unit and check for secure connections.

There might be an outside chance your ignition switch is wearing out. Internally, the connections may be grounding out on each other.
