[QUOTE="Lazarus, post: 885447, member: 323322"] Higher Gain is better. The figure refers to Gain relative to a half-wave dipole, which is deemed to have a Gain of 0 dB Another way of quoting Gain uses an Isotropic Antenna as the reference (ie An Antenna that is wholly omni-directional {or radiates equally in a spherical pattern}). As a dipole has a theoretical gain of its own in relation to an Isotropic Antenna - of 2.4 dB - then that can be used to mislead if the reader is not wholly aware of the reference being used. Strictly, the figure relative to Isotropic is quoted in dBi. Either way, more is always better for Satellite Dishes! [/QUOTE]
