No, radio antennas only pick up electromagnetic waves. Ultrasound is mechanical pressure waves, you need a microphone to pick them up.
1). If it's getting any FM stations, then the radio is OK.2). If it's getting the strong (nearby) stations but not the weak (far away) ones,then check the car's FM antenna, the connection between the antenna and thecable, the condition of the cable from the antenna to the radio, and the connectionbetween the cable and the radio.
Your antenna lead-in is broken, and the radio isn't getting any signal. That's why it keeps scanning and can't hear anything. Check the connection from the antenna to the cable, and if that's OK, then you'll have to replace the cable from the antenna to the radio. You did connect the antenna to it when you were checking it in the first car, right ? You can quickly test this hypothesis: With a radio in the first car, where no radio works, connect the power, but don't connect the car's antenna to it. Instead, stick the end of a different piece of wire ( 3 to 6 ft long) into the center hole of the antenna connector on the radio, and see if that makes it possible for the radio to start hearing things.
The radio antenna is a fine wire imbedded in the windshield. If your radio doesn't pull in any stations, but you get static then probably the cable came out of the back of the radio. If you recently got a new windshied it may have not had the antenna. You should be an antenna at an auto parts store and install it on the front fender.
Any antenna can receive anything, but not very well unless it's the correct length for the frequency you're trying to receive. Yes, this antenna will work well so you will not need a special FM only antenna.
It's called polarization and it relates to the orientation of the transmitting antenna. If the transmitting antenna is vertical, the majority of the transmitted energy is vertically polarized so it stands to reason that to pick up the most signal the receiving antenna should be the same way. In a moving auto though more is now understood about the propagation path the signal takes before it actually gets to the moving radio. The signal isn't line of sight but takes a lot of reflective paths before it actually gets to the antenna. The signals are reflected so many times that polarization is altered and can be any direction by the time it gets to the car receiver. Radio stations get around this anomaly by circularly polarizing the signal at the transmitting antenna. Many car antennas are now embedded in the glass windows instead of wire whips formally mounted to the fenders.
Your VW Passat stereo will not pick up any radio stations if the antenna has come loose. The retractable antenna may also be stuck in the down position which severely limits its ability to pick up stations.
Any regular piece of wire will do.
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
Your radio is either broken and you need a new one, or you need a new antenna.
i think our head set acted as antenna..
Comparable or compatible? Any CB antenna with a PL-259 connector is compatible.

It is not going to hurt to ground it with a secondary ground if you suspect it is not grounded. It is not grounded thru the antenna. Just run a ground wire from the radio chassis to any ground location.It is not going to hurt to ground it with a secondary ground if you suspect it is not grounded.

If the radio and antenna are both malfunctioning on a 1998 4 Runner their may be an issue with the wiring. Check the wire with a spark tester and see if there is any current flowing through it.
