Hello Antenna builders
This is the, new 2008, improved version of my helical antenna programme.
The main changes are to the "Help" pages. You can now scroll line-by line and
the "help" pages can be written out to an ASCII file. You can also save the
design data to a file. There are a few other minor changes as well.
HELIX.EXE is a design programme for axial mode helical antennas.
It gives dimensions for three different design methods. If you are an
optimist the you will believe the gain from the J.D.Kraus formula.
If you believe in computer models then you can believe in Dr Emerson's
gain figures. If you are a realist then the King/Wong gain figure should
be believed.
It is a DOS programme that runs OK in windoze up to and including win xp.
It needs a VGA colour monitor because it operates in graphics mode.
It won't work with other types of monitor.
It needs DOS 4 or later. (Tested with DOS 4.0,6.0,7.10 and 8.0)
It also uses the maths co-processor, so you will need a 486 or better PC.
Help and information are contained within the programme...no separate DOC file.
The programme is freeware for Radio Amateurs.
As usual, there are no guarantees or warranties for this programme. Use it
at your own risk.
73's from Ralph VK2ZRG@VK2WI.#SYD.NSW.AUS.OC
