This is noise coming from a source within the receiver - either the radio or cassette section (noise from a CD transport is very rare). If you determine that the noise originates with your radio antenna, an antenna filter (like American International's AS100) plugs in between the antenna and your receiver to stop (or minimize) noise from entering your system.
The radio is grounding through the antenna connection. Unplug the antenna and see that it will stop. However you still need to hook up the ground 1st and the antenna last.
its shy?
Wind noise reduction and stability. When engineers first designed tall circular towers (such as industrial boiler flues for factories), they ran into a problem - wind currents whipping round the towers would create strange forces that shook the tower from side to side, undermining its structural integrity. They discovered that they could solve the problem by adding a spiral round the top of the tower. It breaks up the wind currents and balances them out. The same problem and solution has been found in some steel suspension wires on bridges. So, the spiral on a car antenna is there solely to reduce wind noise and stop the antenna vibrating. It has absolutely no effect on the antenna's ability to receive radio frequency signals.
humming noise is a bad ground to the radio. you may have a loose connection. connect a ground wire to frame of truck.
engine noise coming thru the radio is caused by a bad ground somewhere so instead of chasing that you go to a car stereo shop and buy a noise filter that hooks up to the ground wire coming off the radio.
the antenna its self will have a connector you can unhook
stop noise become wise

First physical pull the antenna all the way up, clean the antenna very good with a degreaser, then lubricate it with a silicon spray. Open the trunk, unplug the power to the antenna, start your car with the radio turned on, stop the engine, plug the power source to antenna back in. Try it now, if you still have the same problem, either the relay is stuck and needs replacing or the antenna motor is shorted and needs to be replaced.
