Introduction    ↑   → 

Determin the inductance of loading coils to shorten the length of a vertical or dipole. A calculator programmed in LabVIEW.

List of Features     ←   ↑   → 

• Locate coil anywhere between the feedpoint and 90% of the end.
• Free-running loop. No tedious single-shot action.
• Formula from QST, September 1974

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.

1. Download 1st:  LabVIEW Runtime Engine 
   • This is the interpretor program.
   • Or, should it please you, the entire LabVIEW programming environment.
   • Link back to ky8d.net/free where I give download instructions.
2. Download 2nd:   ZIP  
3. Important! Best to employ a stand-alone ZIP archive software (like  7-Zip ) for extracting the *.exe file. Otherwise, Windows will issue dire warnings of an unrecognized app. Once extracted from out of its archive, however, Windows will know to pass it off to the LabVIEW Run-Time Engine instead.
4. Source Code, for any who want it.
   • Do with my LabVIEW code just as you please. Credit me or not as you choose. Do please pass along any credit I’ve given to other sources.
   •  Source  The LabVIEW source code.

Caveat Mutuum     ←   ↑ 

Latin for “Let the moocher beware”. I designed this for me, and used it with glee. I share it here with you for free, but offered without even so much as the smell of a dead warrantee (or wheriot, as the case may be). Whatsoever disasters of cosmic proportion as may result from the use of this program, any and all culpability rests wholly and solely with the user.
