Is your zip 02170 and are you trying to pick up ch. 64 out of Providence? A db8 uhf antenna might do the job but a vhf antenna rated for the blue zone would be best since your area has several digital channels on vhf frequencies. Ch. 64 is actually using ch. 12 to broadcast it's signal btw.
You'll also want a quality uhf antenna for everything on the higher (uhf) frequencies, then combine the two antennas with a cm7777 preamp. Two of the best uhf antennas are the 91XG and the
db 8. SummitSource.com seems to have the best prices on antennas and the cm7777 preamp but I don't think they sell the 91XG model.
One more thing, I don't believe there are any antennas rated for the violet zone. To achieve that you take a blue zone antenna and add a good preamp to achieve the violet rating.
