Aerials designed for indoor use square measure typically poor performers as a result of they're tiny and have few "elements". Size matters - do not let anyone tell you that it doesn't! Most "indoor aerials" have very little or no gain however makers attempt to hide this truth by incorporating a "high-gain booster" then jactitation that the aerial has, say, "a twenty dB gain" once really it's nothing of the kind.
This type of aerial with unsupported reflector stubs is helpful solely as a loft aerial. it's simply bent by birds and wind, thus i do not suggest it for outside use unless it's a sort that encompasses a robust supporting frame or a mesh style.
Note that this one is incredibly short thus, despite doable claims to the contrary, it's a really low gain and is helpful solely during a robust signal space. Length is most vital.
The Vision "Focus" V10-040 log-periodic in situ.
It has no reflector and isn't simply broken by birds or wind.
