1252AG-T-K9 antenna gain

[Rosa Ladeira]

What is the best antenna gain configuration in order to improve low signal ?

Antenna Parameters
Antenna Type       External
Antenna A B C
Antenna Gain   x 0.5 dBi

 Is it possible to configure diversity reception ?

[Leo Laohoo]

Antenna gains depends on the antenna you've got.  If you have an antenna with a gain of, as an example, 3.0 then the value you enter is 1.5. 

Majority of the time, we just leave this value at default.

[Rosa Ladeira]

zero is the value.

Is it the default ?

Some antennas are rated in comparison to dipole antennas. This is denoted by the suffix dBd. Hence, dipole antennas have a gain of 0 dBd (=2.14 dBi).

Note that the majority of documentation refers to dipole antennas as having a gain of 2.2 dBi. Theactual figure is 2.14 dBi, but is often rounded up.
