1-Why the antenna of the radio of cars is located outside the car and not inside?
2-If the answer to 1 is because that cars are like Faraday cages then how come my cell phone can receive signal inside the car?
3-To receive a strong tv/radio signal the antenna must be oriented in a specific way. Why the strength of the cellphone signal seems independent of the orientation of the cellphone?
4-It seems to me that the length of the antennas of cell phones or that of a tv or radio is of the same order as the corresponding wavelength used, why is that?
