Hi Francis,
does TMM tell you 'weak hardware' or 'not supported' - or does nothing happen when you plug in a Catalyst antenna?
So the configuration comes technically after the basics checks that verify your hardware.
Also what configuration is not working for you?
Generally speaking the best way to diagnose such issues is sending an email via TMM to Catalyst support (the default email when you go to the About screen in TMM). This email contains an attachment with logs in case of issues.
Tom wrote a good article on how to do this:
