About antenna modeling softwares, MMANA GAL is good software, but only for learning and playing. MMANA-GAL is an antenna-analyzing tool based on the moment method, which was introduced in MININEC. However, the "Garbage In, Garbage Out," rule applies especially well to MMANA and other antenna modeling programs. NEC Lab - NEC Lab is a powerful tool that uses Numerical Electromagnetics Code (NEC2) and Artificial Intelligence (AI) to design antennas. The problem is that if you live in a country that uses a comma instead of a dot for indicating decimal numbers your machine (Windows or Apple OS) will output a file for MMANA using commas which will not be recognised by MMANA. This 2m 8 element beam was designed and built by Jaybeam in 1970, we saw the MMANA-GAL prediction for it's performance and Mike summed it by saying that Jaybeam did a really good job without the use of computers for modelling at that time.
