EZNEC Pro/2 NEC-2 Based Analysis Program
EZNEC Pro/4 NEC-4 Based Analysis Program

 
 

EZNEC Pro v. 5.0 programs are full-featured 32-bit Windows applications

Please Note: EZNEC Pro v. 5.0 does not function under Windows 95 or NT 4.0. All other 32- and 64-bit Windows operating systems are supported: 98, ME, 2000, XP, and Vista.

EZNEC Pro/2 is a complete,  easy-to-use analysis program which uses an integrated version of NEC-2 for calculations. Several of its many features are shown below.

EZNEC Pro/4 has an identical user interface to EZNEC Pro/2 and with identical features except that it offers the additional options of internal single or double precision NEC-4 calculating engines. An NEC-4 license must be purchased from the NEC-4 copyright holder before purchasing EZNEC Pro/4.

In both EZNEC Pro programs, the antenna description is entered using the popular EZNEC interface method of spreadsheet-like entry and powerful editing tools, or EZNEC Pro can directly read your existing NEC description file. The internal calculating engine is automatically called when needed and the results displayed. No exiting, file converting or editing, or similar operations are required.

• Full 32-bit Windows graphical user interface.
  
• Spreadsheet-style entry of all description parameters. Fast, easy description modification.
  
• Three-dimensional far field patterns with positionable cursor. Any azimuth or elevation "slice" can be highlighted and analyzed in detail in a two-dimensional display, or recalled for later analysis without recalculating. Multiple 2D "slices" can be superimposed and compared. Linear and circular polarization components can be shown..
• Three-dimensional, positionable view of the antenna, with currents and other important information.
• Automatic geometry check to prevent illegal wire connections, crossing, and overlap.
  
• Automatic segmentation check to alert you to accuracy-degrading conditions.
• Many advanced editing features to speed and simplify creating and modifying models, including automated radial wire, helix, loop, and rectangular wire grid creation.
• Near field and ground wave analysis.
• Plane wave excitation.
• Transformers, parallel connected loads, L networks, and Y parameter networks.
  
• True current sources, transmission lines (optionally including loss), and open- and short-circuited stubs.
• Frequency "sweep" from external list of arbitrarily spaced frequencies, or internal steps.
• Comma-delimited data output for easy importation to other programs, as well as formatted text outputs.
  
• Description merging and ASCII file wire importing features.
• Intelligent determination of memory use. Allocatable arrays cause use of disk as virtual RAM only if all available memory has been used.
• Comprehensive, instantly available help. Printable manual is also furnished.
• Fully compatible with EZNEC files.
• Can analyze antennas with up to 20,000 segments.
• Writes IONCAP/VOACAP Type 13 files.
  
• Ability to directly read and translate NEC input files. The following "card" types are read: CE, CM, EK, EN, EX, FR, GA, GD, GE, GH, GM, GN, GR, GS, GW, GX, IS, LD, NE, NH, NT, NX, RP, TL, XQ.
• Ability to write files in NEC format.
• Saves plots in standard OpenPF format for compatibility with TA and other programs.

EZNEC Pro and NEC

Although EZNEC Pro incorporates NEC-2 or NEC-4 (EZNEC Pro/4 only) as its calculating engine, it operates as a single, integrated program rather than as a "pre-" or "post-processor" for NEC. The included NEC code isn't user accessible. No NEC-format input or output files are generated during operation with the NEC-2 calculating engine. Although communication with NEC-4 is largely by means of NEC-format files, these are not generally available except after exiting EZNEC Pro. EZNEC Pro uses its own easy-to-use antenna description file system which has been proven by a large number of EZNEC and EZNEC Pro users, although it is able to both read (to a limited extent) and write NEC-format files. EZNEC Pro incorporates SOMNEC for a complete Norton-Sommerfeld ground solution. Some NEC capabilities aren't presently included in EZNEC Pro, including patches, wire arcs (unless read from a GA "card"), symmetry, and catenary wires. No source code is included or available.

Trial Period

If you are not completely satisfied with EZNEC Pro, you can return it within 90 days for a full refund.

Additional EZNEC Pro/4 Information

Important note:  EZNEC Pro/4 contains its own specially compiled version of NEC-4, so no external NEC-4 program is necessary. However, an NEC-4 license is required for purchase. EZNEC Pro/4 can be sold only after confirming that an NEC-4 license has been issued to the purchaser by the University of California (Lawrence Livermore National Laboratory). NEC-4 can now be sold outside the U.S. Visit https://ipo.llnl.gov/technology/software/softwaretitles/nec.php for information about obtaining an NEC-4 license.

EZNEC Pro v. 5.0 is ready for immediate shipment. For more information contact w7el@eznec.com.
