Whether or not the radios narrowband is irrelevant. The OP is looking to use in the T-band which was exempt from narrow band mandates.

I'm not sure where you're getting T-Band from, OP spec'd the entire UHF band in his request. More to the point, T-Band is NOT exempted from narrowbanding:

Depending on how you intend to use these radios, I would look up the environmental (usually MIL-STD) rating of the radios you are considering to see if they are satisfactory.

OP actually stated 470-512 MHz in his post. He has since broadened the requirements.
However, I'm not aware of a single /\/\ radio that will currently cover 450-512 MHz. In fact the only radios I know that will are Baofengs.
