Lets see, 1 watt transmitter times 9dB gain gives 8 watts eirp. 3dB loss gives 4 watts eirp. That just makes the limit. If you do not have the 3dB loss you might be illegal.

Some of the channels used are in the Amateur Radio 2.4 GHz band. If you exceed the legal EIRP, you need a Ham license and need to Identify your transmission with your callsign.

When using higher gain for greater distance, range is limited by the turn around time off the system software. There is presently no way to change this that I know of. Just because this equipment is made and sold doesn't mean that it is leagle to use it without the proper license.
