28DBI High Gain Wifi Antenna 50Ω 1575MHZ GPS Wifi 4G Waterproof Combined Antenna
Product information:
High-gain antennas are focused antennas with narrow radio beams,
allowing for precise targeting of radio signals. This antenna is
used in space missions as well as in flat, open areas where the
geography won'tdisrupt radio waves.

High-gain antennas can also be produced from parabolic antennas,
phased arrays and yagi antennas. Antenna gains are defined with
respect to hypothetical antennas that radiate equally in all
directions – the isotropic radiator. This gain can be measured in
decibels (dBi) or, in certain cases, decibels compared to the
maximum intensity of the direction of half-wave dipoles (dBd).
Antenna gain refers to the ratio of the power density of the signal
generated by the actual antenna and the ideal radiating element at
the same point in space under the condition of equal input power.
It quantitatively describes the degree to which an antenna radiates
concentrated input power. The gain is obviously closely related to
the antenna pattern. The narrower the main lobe of the pattern, the
smaller the side lobe and the higher the gain. Antenna gain is used
to measure the ability of the antenna to send and receive signals
in a specific direction. It is one of the most important parameters
for selecting a base station antenna.
