or if u want get a shorty antenna from discount auto they work pretty good. i replaced a power one on my camry but my 240 now has a big whip one which ill replace later on since i almost run into it all the time. they make ones that are like a foot tall and dont look so bad. they probly run about $15. if u can figure out what is wrong with your power antenna you will save money by just buying the shaft or just the motor. my shaft ran about $80 for the camry alone

(toyota has highest parts prices of big jap companies). you can also do ebay like other dan said.
