I believe that the answer will depend on what are you expecting from the antenna performance. I mean, if the antenna is intended to be used in an urban environment (like an apartment), I might answer that the best option is an active antenna with a small size and a good gain (around 20 dB for the entire band), that could be used indoors. Nevertheless, if you prefer a passive antenna for a house I might answer you that a good choice would be an arrangement of bow tie dipoles with a metallic grid reflector which in my testing experience has a very good performance (ROE < 3 and a gain of approximately 10 dBi). Some new designs are based upon the fractal antenna technology, and also shows a very good performance. You also will need to keep in mind that the antenna is not the only thing that matters, it is also important to guarantee a good matching between the antenna and the coaxial line (75 Ohm), therefore the majority of the digital TV antennas have a impedance transformer (300 Ohm -> 75 Ohm).
I hope you find this answer helpfull.
