Ferrite Antenna Rod

The Ferrite Antenna Rod is primarily used in radio antennas and universally used in portable transistor broadcast. This is also used in many hi-fi tuners where reception on the long, medium and possibly the short wave bands is required. The antenna consists of a rod made of ferrite and an iron based magnetic material. A coil is wound around the ferrite rod and this is brought to resonance using a variable tuning capacitor contained within the radio circuitry itself and in this way the antenna can be tuned to resonance. As the antenna is tuned it usually forms the RF tuning circuit for the receiver, enabling both functions to be combined within the same components, thereby reducing the number of components and hence the cost of the set.
