FERRITE RODS
2300u Ferrite Rods for DC - 200 KHz

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

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 2300u ferrite rods are great for use at frequencies from DC through 200 KHz.

    LONG PLASTIC COATED FERRITE RODS

    long ferrite rod

    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.

    125u Hi Q NiZn Ferrite rods for 10 KHz - 10 MHz. Long Wave, AM, Shortwave, HAM.

    These rods are excellent for AM broadcast band reception.
