what does dBi mean for a wifi antenna? higher the better???
i need to buy a new antenna for my pci wifi card due to moving my pc
does the higher the dBi number mean better reception?
dBi is “decibels relative to isotropic radiator” which means that the radiator (an antenna, usually) sends the signal equally strong in all directions, including above and below.
So Higher the dBi the greater the signal
