Sub-Hertz Antennas in this range are useful for specialized remote sensing applications such as instantly detecting earthquakes.
Connection is easy, connects to any oscilloscope, millivolt meter, or ohm meter. ELF waves are detected directly output through the standard BNC jack. You can use a data-logging meter or oscilloscope to record ELF emission events of interest.
Use it to detect geomagnetic storms, solar flares, earthquakes, auroras, passing traffic, ferrious metals in motion (metal detector), etc.
Works as a seismograph pickup having no need of moving parts. It detects ground movement by using Earth's magnetic field. Instant real-time detection of distant earthquakes has been observed in some types of large earthquakes. Large arthtquakes can directly modulate the Earth's global magnetic field, e3ffectively producing ELF waves that radiate away at light-speed. When this occurs you detect the quake before the much slower ground motion waves arrive minutes later. You also can observe the actual physical waveforms of the earthquake.
Sub-Hertz Antennas are useful in detecting geomagnetic storms. The slightest movement of earth's magnetic field is registered by these instruments. These antennas can be applied in many scientific research applications.
These antennas are sensitive between 0.009 Hz to 10 Hz. They feature compact size 24 inches long, light weight, and a standard BNC output jack for connection to oscilloscopes or other instrumentation.
25000 ohms output impedance at 1 Hz, 0.01 Hz-10 Hz.
50000 ohms output impedance at 1 Hz, 0.009 Hz-9 Hz.

Antennas in this range are useful for specialized remote sensing applications such as detecting earthquakes without needing moving parts or mass at rest. They are also useful in detecting geomagnetic storms. The slightest movement of earth's magnetic field is registered by these instruments. Earthquakes can modulate earth's magnetic field and be detected at the speed of light via the ELF waves, minutes before the seismic waves arrive. The Ridgecrest, California quake was detected in Texas before the seismic waves arrived from California. These antennas will find many uses in research applications.
This antenna is sensitive to 0.3 Hz to 300 Hz. It features compact size and a BNC output jack
2000 ohms output impedance at 1 Hz. Self Resonant at @ 212 Hz.
Use it to detect geomagnetic storms, passing cars, trucks, earthquakes.
Will work as a seismograph pickup having no need of moving or balanced parts. It detects motion of the ground through the Earth's magnetic field. It is also possible under the right conditions to detect distant earthquakes, especially the larger ones over 7.0 if they modulate the Earth's magnetic field. This means you will see the earthquake on your chart recorder before any of the seismic waves arrive locally.

NOTE: These antennas are bi-directional having a 'figure 8' pattern.
These antennas are sensitive in the range 0.02 Hz to 30 Hz, They feature compact size and a BNC output jack.
Over 10000 ohms output impedance at 1 Hz.
These antennas are 24 inches long and 3.95 inches diameter. Weighs @ 13 pounds.
Use it to reserch geomagnetic storms, earth's core, passing cars, trucks, earthquakes, and a multitude of other ELF wave emissions below 35 Hz.
Will work directly as a very sensitive seismograph that has no moving parts. It simply detects motion of the ground using the Earth's magnetic field. It is also possible under the right conditions to detect distant earthquakes, especially the large ones over 7.0 if they physically modulate the Earth's magnetic field, and it does happen. You will potentially see the earthquake instantly - at the speed of light - on your chart recorder before the very much slower physical seismic ground-shaking waves arrive. The antenna will detect the actual waveform of seismic waves as there is no balanced resonant mass involved. No maintenence of any moving parts ever because there are no moving parts!

These 36 inch long ELF antennas are for detecting movement of geomagnetic fields, geomagnetic storms. They are also useful in seismographs, ELF reception, ELF tuners, and magnetic motion sensors.
These compact ELF Band antennas offer high sensitivity and wide bandwidth.
Directional pattern allows you to zero-in on desired signals.
"Figure 8" reception pattern.
Weather-proof plastic case.
For instant ELF reception, without needing any pre-amplifiers, we suggest using the DI-2008 PC data logger from www.dataq.com. It has the required millivolt input sensitivity. Just connect the antenna to the input terminals and plug the data logger into your computer's USB port. You will be able to detect geomagnetic storms, earthquakes. Can instantly detect large earthquakes without having moving parts in your seismograph. (Large earthquakes modulate earth's magnetic field, for instant detection hundreds of miles away, without the time delay of waiting for the far slower seismic waves).
For use in
If this antenna is used in a moving vehicle and connected to a millivolt meter, the meter will indicate strongly when the antenna passes over a buried iron pipeline or other metal under a roadway. Strong signals well over 1 volt can be generated depending on the strength of the magnetism in the buried metal.
The antenna will output a DC voltage (in millivolts) when moved through earth's magnetic field, or if earth's magnetic field moves, as happens during geomagnetic storms and earthquakes.
Binding posts allow quick connection to voltmeter or data logger terminals.
