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.

Laminated Silicon Steel Rods
for lower frequency applications
Plastic Cased Laminated Silicon Steel Rods
These silicon steel rods are excellent for weak signal reception between 0.01 Hz through 10 KHz. ELF, SLF, ULF, VLF.
Wind ELF and VLF antennas and coils using this strong high 'Q' magnetic material.
Benefits of our plastic coated silicon steel rods:
No rough edges that could cut your wires.
No electrical short-circuit to the steel.
Weather-proof and Water-proof.
Environment will not contaminate quality (Rust proof).
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 metal.
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 silicon rod length.
