Modelling STLs (magloops) on computer.

The theory, formulae, a spreadsheet and a BASIC listing for STL calculation are included elsewhere. Here I am listing software, or software links for designing or modelling magnetic loop antennas.

DOS modelling programs

G4FGQ has written a range of DOS programs for working out /modelling Triangular, Square, Hexagonal, Octagonal, Circular Rectangular transmitting loops, and frame receiving loop aerials. All three programs are very simple to use, an very compact. So far they produce comparable results to the spreadsheet but with the additional factor of height above ground.
If you want one, you get all three as I have zipped them together into a tiny 35kB file G4FGQLP.ZIP .

Another DOS loop design program

Hans J Kromer DK1NB has put together an excellent suite of loop programs and includes some suggested designs - the variable tube capacitor is a particularly tempting creation. You can grab this freeware program from The Simtel.Net MS-DOS Collection under simtelnet/msdos/hamradio/. The file is mloop31.zip,

(there are other ham radio morsels there worth looking at too). Its a bigish file (400,742bytes), and runs in DOS - with a minimum VGA screen and is very flexible in function.
