Above: Screen shots from several EZNEC displays. Right: 3D far field pattern, with 2D elevation "slice" highlighted. Any azimuth or elevation slice can be highlighted. Center: View Antenna display, showing the "wires" making up the model of the five-element beam, with currents and 2D slice superimposed to show orientation. Several other items, such as currents and wire numbers, can be added to this display. Left: 2D display showing detailed information about the selected slice.
All features which were available in EZNEC Pro/2 v. 6.0 are incorporated into EZNEC Pro/2+ v. 7.0 with a few exceptions described below. EZNEC Pro/4 v. 6.0 was identical to EZNEC Pro/2 except for the inclusion of an internal NEC-4.2 calculating engine. That also holds true for EZNEC Pro/4+ and /2+.
External calculating engines - Both EZNEC Pro/2+ and EZNEC Pro/4+ can use external NEC-4.2 and NEC-5 programs for calculations. After installing EZNEC Pro/2+ or EZNEC Pro/4+, open the manual (Help/Contents) then open the Reference/Additional Information/Calculating Engines topic for detailed information about these and how to get them.
Individual wire loss - Each wire can have different loss if desired.
Improved NEC format file reading - A number of deficiencies were addressed and corrected.
Plot display enhancements - Line widths and object sizes can be changed in the 2D, 3D, SWR, and View Antenna displays.
Charge density table - New Options menu selection to optionally add charge density data to the Currents table.
Example files and Test Drive updates - Example files have been updated to replace MININEC type ground with Real, High Accuracy ground where MININEC ground isn't needed. The Test Drive tutorial has been updated to use the new files and to show values consistent with them and the use of the internal NEC-2D calculating engine. Original versions of example files which were changed are in a Legacy subdirectory.
Undo Calculating Engine Change - Certain features are automatically enabled or disabled, and items such as a second ground medium can be deleted when changing calculating engines. So calculation engine changes can now be undone or redone.
Wire Segment Intersection Conversion - Descriptions containing wires intersecting at segment junctions can automatically be converted to the now-required wire end connections.
