EZNEC Pro/2+ and Pro/4+ v. 7.0.4 are now available. This revision enables, for the first time, the inclusion of wire insulation loss in models when using an external NEC-5 calculating engine. (Lossless wire insulation for NEC-5 was introduced in EZNEC Pro/2+ and Pro/4+ v. 7.0.3.) Wire insulation capability is not built into NEC-5 but is available only when running NEC-5 with EZNEC Pro+. No modification of or update to NEC-5 is required.
For more information about the significance of wire insulation loss (loss tangent), see the comprehensive posting by Dan Maguire, AC6LA at 'New EZNEC update v. 7.0.4'.
v. 7.0.4 also corrects several bugs. Details are in the Updates page.
Previous revisions of EZNEC Pro+ v. 7.0 can be updated to v. 7.0.4 by downloading and running either the full program installer or the appropriate update installer. Neither requires uninstalling an existing copy of EZNEC Pro+ v. 7.0, but EZNEC must be closed while running the replacement or update.
UPDATE INSTRUCTIONS
Important note: The EZNEC Pro/4+ full program installer requires a current EZNEC Pro/4+ v. 7.0 installation or the previous purchase of an earlier version of EZNEC Pro/4, and the number of downloads is limited. These are explained at the information link below. If you have a currently installed EZNEC Pro/4+ v. 7.0 program and have reached your download limit, you can upgrade to v. 7.0.4 by using the update installer.
Important note: The EZNEC Pro/4+ v. 7.0.4 update installer will not run unless you have a previously installed EZNEC Pro/4+ v. 7.0 program on the machine. It does not contain the full EZNEC Pro/4+ v. 7.0 program and it will not convert EZNEC Pro/2+ to EZNEC Pro/4+.
Note: The following situation is uncommon but has happened: If you have, for some reason, installed EZNEC Pro/2+ v. 7.0 after you last installed EZNEC Pro/4+ v. 7.0, the update installer will report that it found EZNEC Pro/2+ and not Pro/4+, and refuse to run. The solution is to run the full program installer of any revision of EZNEC Pro/4+ v. 7.0, after which EZNEC Pro/4+ updates will run. There's no need to first uninstall EZNEC Pro/4+, but I recommend uninstalling EZNEC Pro/2+ before running the EZNEC Pro/4+ installer, since there's no advantage to having both program types.
