There are more parameters to consider when choosing antennas also:

There are more parameters to consider when choosing antennas also:

* '''Antenna polarization'''' is direction in which electric field oscillates while it propagates through environment. It is important to match broadcasting and receiving antennas polarization: it must be same polarity. In this way the maximum signal is obtained. Wi-Fi antennas are almost always vertically polarized, while mobile antennas are either vertically polarized or cross polarized;

* '''Antenna gain''' describes how much power is radiated in the direction of peak radiation compared to isotropic emitter. Different units are used to express antenna gain:

** Decibels (dB) – 10 dB means 10 times the energy relative to an isotropic antenna in the peak direction of radiation;

** Decibels (dB) – 10 dB means 10 times the energy relative to an isotropic antenna in the peak direction of radiation

** dBi (decibels relative to an isotropic emitter) is the same as dB because isotropic antenna has gain of 1dB.

** dBi (decibels relative to an isotropic emitter) is the same as dB because isotropic antenna has gain of 1dB

** dBd (decibels relative to a dipole antenna) – dipole gain has a gain of 2.15dBi so 10dBi antenna has gain of 7.85dBd

** dBd (decibels relative to a dipole antenna) – dipole gain has a gain of 2.15dBi so 10dBi antenna has gain of 7.85dBd

*** Therefore 10 dBi = 10 dB = 7.85 dBd

*** Therefore 10 dBi = 10 dB = 7.85 dBd
