In order to bring you the best giant monster ferrite rod products possible, we are now supplying premium plastic coated shatter-proof ferrite rods.
We are offering brand new ferrite rods of 125u and 2000u permeabilities.
We are adding new "M" 125u permeability ferrite rods in 1-inch diameter size. These operate between 20 KHz to 30 MHz and offer highest Q at frequencies below 3 MHz.
We are also adding "T" 2000u permeability very low frequency ferrite rods of 1-inch diameter size. These operate between 1 Hz to 500 KHz and offer highest Q at frequencies below 20 KHz.
Ferrite rods are made up of special ceramic magnetic materials wherein the magnetic molecules (domains) have the ability to align freely with external magnetic fields. The result is a powerful gain in strength (amplification) of the received radio signal but without adding any electronic "hiss" noise. Its like a pre-amplifier but requires no external power except for the incomming signals.
We have long thick ferrite rods for use in your specialized radio receiver or transmitter. These are not the brittle thin ferrite rods that break easy that you might be accostomed to. Our ferrite rods are made with a plastic coating to help prevent breakage and provide a smooth non-abrasive electrically insulating winding surface.
We have 2 magnetic permeability values of ferrite rods: 125u and 2000u.
125u is a material that works for very low frequency, low frequency, medium frequency, and high frequency.
2000u is a material that works for extremely low frequency, super low frequency, ultra low frequency, very low frequency, and low frequency.
We have ferrite rods in lengths from 4.5 inches long to 27 inches long.
Our 125u ferrite rods are for use in the range of 20 KHz - 30 MHz. (VLF, Longwave, AM, Shortwave).
Our 2000u ferrite rods are for use in the range of 0 Hz - 500 KHz. (ELF, SLF, ULF, VLF, LF, MF).
All of our plastic ferrite rods are weather-proof and water-proof and they resist shattering due to the plastic casing.
Benefits of our plastic coated ferrite rods:
10.1-inch version shown.
High "Q" ferrite rods made from premium ferrite material.
These 125u ferrite rods are for use in the 20 KHz to 30 MHz range. This ferrite material is electrically non-conductive.
This ferrite rod offers excellent narrow band (high "Q") reception, better "Q" than our 2000u rods.
This ferrite rod is for use in super-sensitive antennas, especially the AM broadcast band 530 KHz - 1710 KHz, and in the VLF and longwave bands below 530 KHz.
Chart shows recommended frequency range of 125u ferrite rods.
Circumferance: Holds 4.25 inches of wire per turn.
Length of case: Outer case length is 1.4 inches longer than Ferrite Length.

Prices subject to change without notice. All sales final (So you know you're getting a brand new ferrite rod, not a used or pre-owned one, thank you!).
Shipping/Handling charges are extra, depends on weight and size of box at actual time of shipping.
* Test Frequency is for example: When a coil of wire is wound and centered on the rod: 71 turns of # 22 copper wire and a 151 pF capacitor is used for resonating the coil.
** Test inductance is measured when a coil of wire is wound and centered on the rod: 71 turns of # 22 copper wire.
***Ohms per turn is measured with 71 turns of # 22 wire wound on the center of the rod. Test frequency is 1000 Hz and 120 Hz.
Low Frequency ferrite rods made from premium ferrite material.
These 2000u ferrite rods are for use in the 0 Hz to 500 KHz range.
This ferrite rod offers highest "Q" below 20 KHz.
This ferrite rod is excellent for use in super-sensitive very low frequency antennas below 19 KHz. Use our 125u for 20 KHz and above.
Our 12 inch long part # VFR12T, and our VFR24T are our standard part sizes. Other sizes are listed below.
Shorter lengths (under 10 inches) are generally useful for antenna coupling and small sensors.
Longer lengths (over 20 inches) are useful for extra low frequency applications.
Circumferance: Holds 4.25 inches of wire per turn.
Length of case: Outer case length is 1.4 inches longer than ferrite length.
