Point one. "advertised gain". Be suspicious of any "advertised"
gain figures. Is it dbi, dbd,? Etc
Point two. This might be 2.6 dbi, gain over an isotropic radiator,
a hypothetical antenna. However, nobody uses anything that is an
isotropic radiator. Look up isotropic radiator. Similar to "black body
radiation". Sort of impossible to achieve. However, if the 2.6db gain
were 2.6dbd, (gain over a dipole), you would realize a nearly doubling
in effective radiated power (in a certain direction) over the original
dipole in the same direction.
. Then there is the whole discussion about what it effectively does to
the actual received signal. Worldradio magazine has a monthly column
about "aerials", which constantly discusses these issues. Bottom line,
better antenna, better signal. How much better? That is subjective, even
with the decimal points. Boys and girls? What am I missing here?
Antennas are as mystical as radio itself, and it will be hard to collect
your beer on this one..
