If you have multiple antennas, Amateur radio plates pretty much answer the question of 'what's with all the antennas', before it's even asked.What is the purpose of amateur radio license plates? I recently got mine. Other than look cool, I don't know what they are intended for? Is it to discover call signs for other HAM cars so that you can call them on the radio?
I live in a town with a total population under 3,000. Ain't no hiding anywhere. And my plates mark me even more than amateur plates.To each there own, if someone wants to find you they will....my HAM vanity plate will not make it any easier. And if it does, oh well, come on by, I live in a town of 10K, most everybody knows who I am, what I do and where I live anyway. I am not trying to hide. I can't, even if I wanted to.
Even in Tennessee, an ARES ID is only necessary to have the extra fee for amateur plates waived.Amateur Radio is considered apart of the emergency management community, I would say at least 75% of amateur radio operators are part of ARES=Amateur Radio Emergency Services, Skywarn/storm spotter/trained chaser or some kind of EmComm=Emergency Communication organization. In Most states you have to show a current ARES ID card to obtain this tage. Look up the history of amateur radio in EmComm.
At one time back in the 90's I had amateur plates on my truck (WL7MN). The only thing it ever did for me was get a few .... .. from passing amateurs.An now that you have call sign plates, you need to learn how to tap out "HI" on your cars horn. I don't do that with my truck (94 F-150) because the horn, among other things, doesn't work.
