How to improve radio signal strength

The telescopic antennas on portable FM radios are usually too short. Adding a conductor to the end to increase the length will usually improve reception. As long as it's metal and connected to the antenna end it'll work. Any total length greater than about 2'6" will not bring any further benefits.

will it only work on AM?
