Modeling the W6NL 40m MoxonGreg Ordy, W8WWVApril 13, 2012V1.01• “Re-design of a Moxon rectangle that employs a steppeddiametertaper schedule is not a task for NEC-2. Because thestepped-diameter correction of NEC-2 implementations doesnot operate for non-linear elements, the program will notcorrectly handle the bent Moxon elements. Re-design shoulduse either NEC-4 or a highly corrected version of MININEC3.13, such as the one sold as Antenna Model”.
