Long Ferrite Antenna Rod Elements LW, VLF, ULF, SLF, ELF.


long ferrite rod

We are offering brand new ferrite rods in 125u, and 2000u permeabilities.

Ferrite rods concentrate magnetic fields and radio waves, especially useful at lower frequency. They are easy to use as a directional antenna: just wind turns of wire on the rod and then connect a capacitor to tune it to desired receive frequency.

We have 2000u permeability "T" type very low frequency ferrite rods of 0.845 inch diameter size. These are new 2nd generation solid core rods and are best for use in the frequency range between 0 Hz to 500 KHz. 2000u is a material that works at extremely low frequency, super low frequency, ultra low frequency, very low frequency, and low frequency.

125u ferrite rods are for use between 100 KHz to 3 MHz. This range includes the AM broadcast band.

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 incoming 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 familliar with. Our ferrite rods are made with a plastic coating to help prevent breakage and provide a smooth non-abrasive electrically insulating winding surface.

We manufacture plastic ferrite rods in lengths from 4 inches long to 36 inches long.

Sales to USA only. Not for export.

2000u Monster Ferrite Rods
for lower frequency applications

FERRITE RODS for Extreme Low Frequency ELF, Super Low Frequency SLF, Ultra Low Frequency ULF, Very Low Frequency VLF, and Low Frequency LF. Working range DC - 500 KHz.

These 2000u ferrite rods are excellent for weak signal reception below 530 KHz.

Benefits of our plastic coated ferrite rods:

  • Won't break in pieces if stressed.
  • No rough edges that could cut your wires.
  • No electrical short-circuit to the ferrite. (2000u ferrite material is semiconductive).
  • Weather-proof and Water-proof.
  • Environment will not contaminate ferrite quality.
  • Clean to handle.
  • Smooth clean white plastic surface gives high contrast so you can easily see your wire work.
  • Plastic case is 1/16ths inch thick. Your antenna coil is electrically insulated from the conductive ferrite.
  • Circumferance: Holds 3.5 inches of wire per turn. (Example: 103 turns requires 30 feet of wire).
  • Length of case: Outer case length is 1 inch longer than ferrite rod length.

    Low Frequency ferrite rods made from premium ferrite material.

    These 2000u ferrite rods are for use in the 0 Hz to 530 KHz range.

    long ferrite rod

    A monster ferrite rod like this one is waiting to make your receiver roar! You'll discover weak DX signals you didn't know where there! You'll have one signal-pulling monster of a radio without the hassle of a big outdoor antenna! Ferrite rods detect the magnetic field part of the low-frequency radio wave which can easily pass through most home building materials. These magnetic fields are strong at ground level so you don't need to elevate the antenna to get improved reception.
