Indoor antennas are iffy. The reasons are #1) the structure's walls diminish the signal strength and #2) compromises are made so that the antennas look better. Since receiving the VHF channels requires larger elements than UHF channels, indoor antennas may have issues with VHF reception.
In Atlanta, if your reception issues are with channels 8 or 11, then you are having problems with VHF reception.
Some people actually use small outdoor antennas and hide them under something. If you are not renting, then you might consider an attic installation.
