xormin: It may or may not be allowed to be used in NZ, I don't know. For the sake of this augment lets say that it is. If you are really worried about it lets say I am using it on my boat to get cell phone reception outside the 12 mile limit (which I could quite legally do). What I am really after is a technical answer to the question.
I really hope you get done now as you don't seem to care at all with the "It may or may not be allowed to be used in NZ, I don't know" comment. You really "should know" and I bet you did but just playing the dumb card.
