What range of MHz to expect from commonly available VVCs
My own (as in yet another) calculator for small-loop transmitting antennas functions differently from all others. Hopefully in a way you will find handy. Focus is chiefly on tuning capacitor. Because once you have either rolled, brazed, or soldered the main loop into a unit whole, there’s no easy way to change that. Also, the loop you can make however you want. Your choices of tuning capacitor, though, can be very limited. Especially if you’re wanting to use a VVC.
Thus I present for your kind consideration my own contestant in an already well-packed arena. Two things it does better than most. Firstly that, for running in a continuous loop, there is no tiresome Calculate button to continually re-click. Secondly is that I have the highest personal confidence in its predictions for loop L (μH) and Cs (pF). This because of employing ultra-modern algorithms recently authored by Robert (Bob) Weaver and David Knight, G3YNH.

⚠️ These labels vary by manufacturer. In Canon’s printing system, F1–F5 refer to fixed, non-editable, printer-resident fonts. You cannot "download" them as separate installable font files—they are firmware-based.
These represent different font styles or typeface families (e.g., Ming, Gothic, Kai) within a CJK CID system.
What do the numbers (F1, F2, F3, F4, F5) signify? While there is no universal mapping, the most widely accepted explanation is that these numbers define the font weight (stroke thickness) of the missing typeface. In many PDFs that use this placeholder system, F1 often corresponds to the regular weight, and F2 to the bold weight, with F3, F4, and F5 representing other weights like medium, semibold, or black. While this mapping is not an official standard, one of the most established interpretations holds that F1 through F5 are used to denote the weight of the font.
Older CAD software, ERP systems, or Japanese/Chinese document processors might require these exact font definitions.
If you only have the broken PDF file, you can try rebuilding it using an open-source command-line tool like Ghostscript to substitute generic fallback fonts. Install Ghostscript on your machine.
To minimize risks, consider:
Download the zipped images. Because images do not rely on font files, the text will be locked in place exactly as it was meant to look. Method 5: Request a Re-Export (If Possible)
You’ll need two things for it to run: my *.exe application itself, plus also the interpreter program on which it runs. Kind of like Java that way, except that the Java interpreter is probably pre-installed on your system. The LabVIEW run-time engine will not be.
ky8d.net/free where I give download instructions. ZIP archive software (like 7-Zip) for extracting the *.exe file to somplace useful prior to trying to run it. Otherwise, Windows will issue dire warnings of an unrecognized app. Once extracted from out of its ZIP archive, however, Windows will know to pass it off to the LabVIEW Run-Time Engine instead.[Insert download link]

*.ods spreadsheets.*.ods spreadsheets.Because I don’t know either BASIC or Python. And my skill in Perl is quite modest; not up to anything quite this complex. Especially not when it comes to the GUI. Even the math itself is largely beyond my poor understanding. Such are my faults. In LabVIEW however, I am fairly comfortable. Thirteen years now, I have put LabVIEW to use in regular support of my job as a test engineer. So I find myself well able to at the very least faithfully instantiate example equations authored by others. So I here tip my hat to the three maestros cited above (my Aussie bush hat to Owen Duffy).
