The antenna pictured as shown is a log-periodic dipole array (LPDA) antenna. Judging by its small stature it is usable at best on UHF channels. VHF channels reception for anything other than local would next to impossible without serious amplification. An antenna for both VHF and UHF coverage would be substantially larger.
On VHF the elements range between 1 meter to a 0.5 meters in length whereas UHF the elements range in size between 0.35 meters to 0.15 meters in length. When you factor in the spacing of the elements required for desired operation the length of the antenna is upwards of 3 meters in length.
As you increase in frequency your range becomes less due to signal propagation effects. This type of antenna the gain increases with frequency as the larger elements act as reflectors for the smaller ones. If you want fringe reception mount this antenna as high as possible and point the small end in the direction of your desired stations.
In the days of analog TV you could get away without too much signal amplification. However with digital TV amplification is necessary so the receiver can lock onto the signal.
