FERRITE RODS

We have ferrite rods for reception and transmission, and high power wireless energy transmission and pick up. See our products below on this page. Of the bare uncoated ferrites we can supply 1000's of pieces for your OEM project.


PLASTIC COATED VLF FERRITE RODS
600 Hz - 60 KHz

long ferrite rod

These plastic ferrite rods are excellent for weak signal VLF reception and LF reception.

POWERFUL 5000u permeability material pulls in VLF and LF signals.

Just 200 wire turns on the 9 inch ferrite rod is enough to hear VLF Tweeks at night, when connected to an audio amplifier of 3-K impedance with 1 millivolt input sensitivity. (Typical microphone-type input values).

Use this ferrite rod to make antennas, tune antennas, tune long wire antennas, match impedances between loop antennas, build an antenna for VLF.

Benefits of our plastic coated ferrite rods:

  • Plastic prevents total breakage if stressed.
  • No rough edges that could cut your wires.
  • No electrical short-circuit to the ferrite.
  • 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 and adjust your wire work.
  • Your antenna coil is electrically insulated from the semiconductive ferrite.

    5000u VLF Ferrite rods for 600 Hz - 60 KHz.

    For use in VLF- LF reception.

    For use in lightning detection receivers.

    Detect Tweeks, Whistlers, and more natural VLF radio waves.

    'Max Turns # 33 AWG' shows the maximum single layer of 33 AWG magnet wire the rod can hold.

    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.


    AM RADIO FERRITE RODS
    125u Ferrite Rods for AM Radio, Longwave, and Shortwave

    Rods with "AMROD" in the part number will work for LW, AM, Shortwave 150 KHz - 7 MHz.

    Rods with "LWROD" in the part number work from VLF and Longwave 10 KHz - 500 KHz.

    Part # ferrite rod

    You can make directional antennas for your AM or Shorwave radio.

    Ferrite rods make compact directional antennas and tuning elements.

    125u ferrite rods operate between 100 KHz to 7 MHz, so they are good for longwave, AM, and Short Wave reception.

    Use them to magnetically couple signals from a long wire and ground connection into your AM radio's built-in antenna, through your radio's plastic case, without opening or modifying your radio.

    Ferrite Rods for DC - 300 KHz

    Part # ROD-038-2750T+
    Part # ROD-038-2750T+

    For extended range wireless energy transmission and pickup. 100 KHz - 300 KHz.

    Ferrite rods greatly 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 variable capacitor to tune it up to the desired receive frequency.

    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 magnetic strength (amplification) of the radio signal but without adding any electronic "hiss" noise. Its almost like a pre-amplifier but requires no external power except for the incoming signals.

    These 2.75 inch x 0.380 inch diameter ferrite rods are great for use at frequencies from DC through 300 KHz.

  • Antennas: Transmits and Receive,
  • Wireless energy transmission and reception.
  • Electromagnet cores,
  • Transformer cores,
  • Audio chokes,
  • RF chokes,
  • Metal detectors,
  • Electromagnetic sensors,
  • Custom inductors,
  • Speaker crossover coils,
  • Experimental motors and more.
