Helical Antenna Tool version 0.02
Jim Cronin N2VNO jdc@cci.com
This windows program was written to simplify choosing helical antenna
parameters. Scrollbars are used to vary frequency, circumference, number of
turns and turn spacing. Antenna gain, impedence, beamwidth, size, etc. are
displayed.
After running HELICAL.EXE under Windows click on 'Edit' then 'Geometry'.
Circumference and turn spacing are in wavelengths.
Displayed values are based on formulas given in the ARRL Antenna Book.
Check the Satellite Antenna chapter for more info.
