H-Field Rod Antennas 100 Hz - 30 MHz

The A.H. Systems' set of H-Field Rods provide an accurate standard for magnetic field testing. The rods are available individually or in a set of four to cover the frequency range of 100 Hz to 30 MHz. For those situations when improved sensitivity is desired in magnetic field testing, the H-Field Rod is an effective alternative to traditional loop antennas. One amplifier pre-assembled to a metallic ground plane covers the entire frequency range and can be used with any or all of the H-Field Rod elements.
