What Determines Antenna Gain?

http://hamuniverse.com/2hentenna.html WebThe gain of a real antenna can be as high as 40-50 dB for very large dish antennas (although this is rare). Directivity can be as low as 1.76 dB for a real antenna (example: short dipole antenna), but can never theoretically be less than 0 dB.However, the peak gain of an antenna can be arbitrarily low because of losses or low efficiency.
