How to study the frequency of royal cubits?

To verify whether the so-called “Royal Cubit” (a ring or other element with a circumference corresponding to the royal cubit) actually “resonates” at the claimed frequency (most commonly stated as approximately 144 MHz), several measurement methods in the fields of radio engineering and high-frequency electronics can be used. Below are some methods and tips.

Using an antenna analyzer

  1. Equipment:
    • It is best to have an antenna analyzer covering the VHF range (e.g., up to 200–300 MHz).
    • Popular models (such as mini-VNA, NanoVNA, RigExpert, etc.) allow the measurement of the standing wave ratio (SWR) and reflection parameter (S11) over a specified frequency range.
  2. Connection:
    • If you have a wire ring with the “Royal Cubit” length, you can try forming a loop and connecting it to the analyzer’s output using a short piece of coaxial cable. It’s important to ensure proper connection (e.g., using a specially prepared holder or coupling probe).
    • You can also use capacitive or inductive coupling – i.e., not connecting the ring directly but bringing it close to a coil or measurement loop of the analyzer to register the frequency at which a transmission minimum (or reflected signal maximum) occurs.
  3. Measurements:
    • Scan the frequency range from, say, 50 MHz to 200 MHz, observing at which frequencies a clear dip (minimum) in the S11 characteristic appears (or a maximum in S21 if two-point measurements are possible).
    • If a clear resonant frequency near 144 MHz exists, it should be visible on the graph.
  4. Result interpretation:
    • If the ring has a well-defined resonant frequency around 144 MHz, you will see a distinct minimum.
    • However, it should be noted that in practice, such a “bare” ring may have more than one resonance (depending on its shape, wire cross-section, contact quality, and environmental conditions).

Using a GDO (Grid Dip Oscillator)

  1. Equipment:
    • A classic GDO (less common today but still found among radio amateurs).
  2. Principle of operation:
    • The device generates an RF signal over a wide range and measures the “dip” in grid current (in older tube-based designs) or an analogous effect in transistor versions when the tested circuit resonates with the generated signal.
  3. Measurement procedure:
    • Place the ring (Royal Cubit) near the GDO’s coil.
    • Tune the generator in the range of about 100–200 MHz and observe whether the indicator (a built-in meter in the GDO) shows a clear dip at some point.
    • Read the frequency (or approximate value from the device’s scale) at this point.
  4. Advantages and limitations:
    • This method is simple but requires some practice, as the GDO demands “good judgment” of the probe’s distance from the tested object to ensure reliable measurement.
    • The accuracy of the frequency reading depends on the quality and calibration of the GDO.

Using a signal generator and field strength meter

  1. Equipment:
    • An RF signal generator capable of setting frequencies in the range of about 100–200 MHz with adjustable power.
    • A simple field strength meter or even a small receiving antenna connected to an SDR (Software Defined Radio) receiver.
  2. Procedure:
    • Set the generator to a selected frequency and place the ring-cubit nearby (a few centimeters to several inches).
    • By changing the generator’s frequency around 140–150 MHz, observe the signal level in the field strength meter.
    • When you hit the resonant frequency, the signal level registered by the meter (or a drop in signal, depending on the setup) may change significantly.
  3. Accuracy:
    • This method is more “workshop-like” and may require a few attempts but allows detecting resonance near the expected band.

Factors to consider

  1. Environment:
    • Resonance may vary depending on whether the ring is held in hand, placed on a table, or its distance from metal objects.
    • The higher the frequency, the more significant these factors become.
  2. Precision of construction:
    • Resonant frequency also depends on the diameter or cross-section of the wire.
    • It is also affected by the quality of connections (if the ring is soldered) and whether there is an oxide layer on the surface.
    • The actual resonance may differ slightly from the theoretical 144 MHz (e.g., 142 or 146 MHz).
  3. Measurement vs. “energetic theory”:
    • In the esoteric or dowsing context, values such as 144 MHz often stem from theories related to sacred geometry or so-called “cosmic harmony.”
    • In strict physical measurement, the resonance may appear closer to 140 or 150 MHz.
    • The resonance might also be weakly noticeable if the ring does not meet exact dimensions or is not treated as a classic resonant circuit.
  4. Repeatability:
    • To obtain consistent results, it is best to perform measurements under identical conditions (same ring position, same distance to the device, etc.).

Summary

The simplest and most straightforward method is to use an antenna analyzer or VNA (Vector Network Analyzer), which allows you to accurately determine where the minimum or maximum characteristic related to resonance occurs.

  • GDO (Grid Dip Oscillator): A traditional tool for radio amateurs – quite simple to use, although less precise than modern analyzers.
  • Generator + probe: A viable method but requires more improvisation and is less “automatic.”

Remember that achieving a perfectly “clean” resonance at exactly 144 MHz may be challenging in practice. Differences of a few MHz are standard, depending on how precisely the ring is made and the measurement environment.

If you want to ensure your Royal Cubit resonates at a specific frequency point, try to find someone (e.g., a radio amateur or high-frequency electronics engineer) with the appropriate measurement equipment. A joint short session with an analyzer will allow you to definitively determine the actual resonant frequency.
