Good advice. The only thing that I would add is that you need to use good quality equipment for the antenna system. This includes the duplexer, jumpers, connectors, cable and antenna. When you have a situation where two transmitters can be on the air at the same time on the same antenna system, you always stand the chance of creating intermod.
