You can order a radio with High VHF, UHF, 700/800, 900, LTE or with any of the two above, Harris has the (it does something we affectionately call DC-Daylight - aka, the entire EM spectrum), SG-XG100 I think does basically everything, 30MHz to 1000MHz.

Low Band is a special case, because of the sheer antenna size, which is huge, and unwieldily low band handhelds are also near useless.

Ignore the ham guys, they dont know much about part 90 (other than they are correct that the Baofeng Radios are probably not type accepted.).
