I was wondering if anybody tried the DigiAir signal meter to tune in their OTA stations with an off air antenna. If so, has it helped you tune in stations that you was having a hard time getting in before? Is this meter able to see weak stations that are too weak for a digital tuner to pick up? I ask this because I want a meter that is sensative just like a satellite meter is in receiving signals that even the signal meter would not show, so that way you know if you are getting any signal at all and have somewhere to start looking for the right location.
