- NEC4WIN95
- NEC4WIN95 is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows 95, 98, NT and 2000. It can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc.
NEC4WIN95 has limitations. They are the same as Mininec3 on which the engine is based.
NEC4WIN95VM is the Virtual Memory version of NEC4WIN95 and allows a number of wires and segments limited only by physical memory
