My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is limited on your model here but I see no one else has responded and thought I would see if I can help here.
From what is described here this sounds like two different problems.This can be due to low voltage from a weak battery or alternator needing replaced or a corroded or damaged battery cable itself.I would have the battery and alternator tested as well as the cables checked for any issues and repaired as needed.
As for the antennae issue this can be caused by a break or damage to the antennae assembly itself or the cables leading from the radio to the antennae.I would have the antennae and cables checked for any damage and repair or replaced the affected component as needed.
Thanks Pete
