From what I have read... you can use the standard TV antenna that mounts outside your house.
I bought my mom a DTV converter box for mothers day. Sometimes we get more channels on the DTV.
Some Tips from Me are
1) Make sure you have a good connection where the wires hook to the antenna. Use a wire brush to clean where the wires attach, then screw the wires down snug.
2) Try to avoid using 100 foot of antenna wire if you only need 50 foot. The less wire it has to go through the more of the signal gets to the TV
3) Point the Antenna properly. You would think that pointing it Sideways of the Transmitter is best. But really you should point it where the Tail End of the antenna points to the transmitter.
To find the direction to point your antenna go to

So Dave does not think you need a fancy antenna. Just a decent antenna.
Keep up the good work.
