The TV antenna in your picture is a rabbit ears (dipole with balun usually) antenna and the figure 8 is likely for UHF.
The 'reflector' may just be for show. If its is actually metal, I cant see its purpose. The figure 8 may be a biquad without a reflector on one frequency but it wouldnt function as a biquad at others. Performance may be okay, in close in areas the main concern is multipath, not signal strength.
