Old computer's PSU gives useful parts for antennas: by Igor Grigorov, RK3ZK

A personal computer has become an ordinary thing in the recent time. Nearly every radio amateur has his own personal computer. With the course of time some computer's blocks fail and are replaced by new ones. Soon the old computer is replaced by a new one. Finally, a radio amateur accumulates faulty computers as well as faulty and unnecessary computer's pieces. But do not throw away the faulty pieces!
