EZNEC-ARRL
is a
special version of EZNEC
which is included on the ARRL
Antenna Book CD. Its primary purpose is to enable viewing and
analysis of the example antennas included with the Antenna Book. EZNEC-ARRL
v.
3.0 is included with the 20th Edition, EZNEC-ARRL
v.
4.0 with the 21st Edition, and EZNEC-ARRL
v. 5.0 with the 22nd Edition. It operates as
a
normal EZNEC
demo program except when a specially "signed" EZNEC
description
file (included on the Antenna Book
CD) is opened. When analyzing a "signed" file, EZNEC-ARRL
becomes a fully functional standard type EZNEC
program. "Signed" files can be modified in any way and analyzed with
full standard EZNEC
program capability. However, EZNEC-ARRL will
revert to demo operation when any file saved by EZNEC-ARRL,
including a modified "signed" file, is re-opened. Any version of EZNEC-ARRL
will function with "signed" files from any Antenna Book edition, and
all files are compatible with all EZNEC program
types.
No
other "signed" files are available except the ones furnished with the Antenna
Book,
and EZNEC-ARRL can be obtained only by purchasing the Antenna
Book.
If you are an EZNEC-ARRL
v. 5.0 user,
you can update your program to incorporate the latest bug fixes and
manual revisions by downloading and installing the latest EZNEC
v. 5.0 demo.
After running the demo program installation, your program will still
operate as the ARRL version rather than a plain demo,
and it will be updated to the latest revision.
If you are an EZNEC-ARRL
v.
4.0 user,
you can update your program to incorporate the latest bug fixes and
manual revisions by downloading and installing the latest EZNEC
v. 4.0 demo.
After running the demo program installation, your program will still
operate as the ARRL version rather than a plain demo,
and it will be updated to the latest revision.
