    2-metre band FM, 144.9MHz-145.1MHz

    The FM Broadcast band is 88MHz - 108MHz.

    Magnetic induction loops are often used for small areas. As for suitable bands, that would depend on where in the world you are.

    You forgot to mention that operation on the 2M band, which runs from 144-148 MHz. requires a valid amateur radio license.
