What are you looking to do in that band? I seem to recall that JerseyNet, the testbed for the FirstNet system, is in place in NJ, and is about the only thing in that frequency range. However it's an LTE system, and the radio you mention above is an analog and LTR trunking radio (LTR is not at all compatible with LTE). Plus, the radio you mention is a very old Motorola model that's not in production any more as far as I recall.
If you're looking to be on FirstNet, you need an LTE compatible radio. There's a small handful who make radios with that compatibility, among them Motorola and Harris, but I don't know of any others at present. JVCKenwood is in the stages of coming up with an LTE/P25 radio, but I don't know if it's out yet.
