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.

What's in a name? I too was confused for a long time. But one is a sub-set of the other. And my calculator does both.
The designation magnetic loop specifies a main-loop circumference necessarily smaller than 0.05 λ, according to some. And by no means larger than 0.1 λ, according to many. Only when thus configured does the antenna enjoy deep side nulls.
Larger sizes still work very well. Better, even, if it's radiation efficiency you value most. The self same antenna, when tuned for higher frequencies, gradually loses its side-nulls while gaining higher efficiency. And therein lies a critical difference. Down low it's a magloop; up high it's only a small loop. The same basic antenna structure, but with two very different behaviors.
And magloops came first, their deep nulls important for use in direction finding. You see them in movies about WW2: atop Nazi trucks roaming through streets in search of French resistance cells; mounted on bombers following a radio beacon aimed out of England toward Dresden Germany to direct night-time fire-bombing raids. There is history in the special distinction.
And so, after having twice now suffered (and rightly so) polite harrangues from others much better in-the-know, I bow to the nomenclature gurus, re-naming my program for what truely it is: a calculator for small loop antennas (among which over-category magnetic loops are a particularly venerable sub-set).
The distinction becomes immensely important as circumference approaches λ/4 and larger. Because now it is hardly even a small loop, but increasingly something closer to curled-up dipole with mutually coupled capacitance hats. And still it will resonate. The radiation pattern, however, will by now be growing a lobe. So that unless it's our goal to shine a warming radiation upon worms or birds, then our capacitor will best be mounted at either three or nine o'clock instead of the usual six or twelve.
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.

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.The story follows a familiar but effective trope often explored in the Real Wife Stories series on IMDb :
The phrase references a notable 2009 episode from the adult entertainment network Brazzers, specifically within their popular anthology series, Real Wife Stories . The episode, titled "Fun with a Stranger," features Canadian performer Kylee Strutt alongside actor Chris Johnson.
Interactions often feature casual conversation and authentic reactions, mimicking real-life encounters. kylee strutt fun with a stranger real wife stories best
Some of her most notable titles include She's Got Big Boobs! , Big Pretty Titties 4 , and of course, Real Wife Stories 4 . In 2011, Strutt made the decision to return home to Canada, officially retiring from the adult film industry.

In this tale, the stranger is a retiring architect heading to see his adult daughter. There is no rush. They talk for three hours. By the time the plane lands, Kylee has his number and a hotel key. What makes this a best story is the twist: she calls her husband from the bathroom before leaving the terminal. His response? “Did he make you laugh? Then go.”
Kylee Strutt appears in Real Wife Stories 4 , one of the most well-known volumes of the series. In this installment, Kylee embodies the archetype of the attractive spouse perfectly. While specifics of the plot may vary depending on the scene, this volume generally focuses on scenarios of infidelity and chance encounters, capturing the magic that made the series a hit. Some of her most notable titles include She's Got Big Boobs
The voice was deep, smooth, and carried a faint, unidentifiable accent. Kylee looked up from her book.
The success of reality-driven series relies on specific production choices that make the content feel grounded and accessible:
In an industry often dominated by heavy makeup and exaggerated performances, Kylee brought a sense of relatability. She looked like someone you might actually see at a grocery store, which made the "real wife" tagline believable.

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).
