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


LONG PLASTIC COATED FERRITE RODS

long ferrite rod

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. .

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.

Large Monster Ferrite Rods
Thick Ferrite of 0.625 inch, 0.845 inch, and 1.020 inch diameters.

FERRITE RODS for 0.1 Hz - 20 MHz

Rods of different permeability values for receiving the following bands:

  • ELF 3 Hz - 30 Hz.
  • SLF 30 Hz - 300 Hz.
  • ULF 300 Hz - 3 KHz.
  • VLF 3 KHz - 30 KHz.
  • LF 30 KHz - 300 KHz.
  • AM Broadcast Band 530 KHz - 1710 KHz
  • Shortwave bands up to 20 MHz.

    These plastic ferrite rods are excellent for weak signal reception.

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

    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.

    Note: The 125u rods of 1.02 inch diameter (marked in yellow) are best for weak signal reception in the AM and Short Wave bands.

    Note: The 800u rods of 1.02 inch diameter (marked in orange) are best for weak signal reception in the lower AM and Long Wave band.

    Note: The 2000u rods of 0.845 inch diameter (marked in pink) are best for weak signal reception in the ELF to LF bands, 0.1 Hz - 200 KHz.

    2000u Monster Ferrite Rods
    for lower frequency applications

    FERRITE RODS for DC - 500 KHz.

    These 2000u ferrite rods are excellent for weak signal reception below 500 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 0.065 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.
