What are the differences between the STANDARD and ENHANCED version of MARS 300 PRO?

The major difference between these two versions is the antennas, namely, the ability to avoid interference in complex Wi-Fi environments. Both versions come with receivers with built-in antennas. The transmitter is also with built-in antennas for the standard version, while external antennas are used on the transmitter for the enhanced version. Normally, the external antennas have a stronger ability to receive signals than built-in antennas.
