Bought this as part of a Christmas gift for a friend who lives in an apartment complex. We first installed the antenna on TV close to an inside wall with no luck. After moving the TV and antenna closer to an outside wall close to a window, some reception was achieved but nothing like what my grandparents get with similar antennas.
