mine had that and eventually the motor burnt out and had to be replaced. :(
I went to Sacramento lexus dealer, they replace the antenna,,, weird sound gone, signal clear, radio works better.. Cost $240 part and label
If you go to outside place about $150 but they may mess up the back trunk to open antenna motor, or your convertible functions will not work best
Second option is changing the after market media interface $300-500 and could also enjoy hd radio, xm... Or Bluetooth, mp3, ipod, itune, pandora, dvd... Ect
