Sensors on Roof?

Someone know what these are?  White cone I think may be compass but small metal device...I don't know.  Sorry for bad photos.

I think you are right about the compass. The other one looks like the base for the cell phone antenna. Is it threaded? If so then it probably is.

Black square may have been a base for a cell phone booster antenna.  I have a little flimsy short (about 6") antenna in the same general position.

Thanks for the replies.  I did not think to count antennas.  I have two antennas already on roof..one for radio and one for cb I guess.

Yes, the white cone houses the magnetic compass sender and the black square has a coaxial antenna connector on it for the cell phone. The other end should be a loose coaxial cable behind the dash.
