Ferrite Rod Stocks

As the name suggests the antenna consists of a rod made of ferrite, an iron based magnetic material. A coil is would 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.

 
The ferrite rod antenna is almost universally used in portable transistor broadcast receivers as well as many hi-fi tuners where reception on the long, medium and possibly the short wave bands is required.

We manufacture ferrite rods in about 50 different dimensions and most sizes are available ex-stock or with minimum lead time for delivery.

Ferrite rods are primarily used in radio antennas.
