First let's make sure that you are using the right type of antenna for off the air broadcasts. You have thrown me off by stating that you are using a crank up Dish Antenna. It sounds to me like you are trying to use a satellite dish to receive regular off the air TV.
Please take a look at the antennas in the pictures below. The top two antennas are for receiving regular off the air TV. The last one is for Satellite TV and will not work for off the air TV. In order to use the satellite dish you must have a satellite receiver and be subscribed to a satellite service such as the DISH Network or Directv.

If you are using the Satellite Dish to try to get an off the air TV signal that is your problem.
The cause to your problem may also be due to the conversion to Digital TV that all stations are undergoing right now. Effective June 12, 2009 all TV stations are required to switch over to digital TV transmissions and to cease broadcasting analog TV signals. Even though the due date is not until June, some TV stations have already shut down their analog signals and are only broadcasting digital signals.
In order to receive these TV stations with an antenna, you need to have TVs that have digital tuners built in to them or need to purchase a Digital TV Converter Box and connect it to older TVs, so they can continue to receive off the air TV signals.
So, if you were getting more channels before and in the last couple of months you are no longer getting the same channels, it could be that the broadcasters in your area have shut off their analog signals.
