An antenna is a completely 'passive' device. It can't radiate more power than you
put into it. But if you know what direction you want it to favor, you can design the
antenna to take the power away from directions you don't need, and concentrate it
in the direction you want.
Antenna gain means the strength of the antenna in its best direction, compared
to a theoretical ideal antenna that's exactly equally good in all directions (known as
an "isotropic" antenna).
What else can I help you with?
What are two units of measurement used to quantify the power gain in antennas?
Two common units of measurement used to quantify the power gain in antennas are decibels (dB) and linear power gain (often expressed as a ratio). Decibels provide a logarithmic scale that allows for easier comparison of power levels, while linear power gain is typically expressed as a ratio of output power to input power. Both units help in evaluating the efficiency and performance of antennas in transmitting and receiving signals.
Which WiFi router is best in a building?
a MIMO router with omni-directional antennas, perhaps with higher gain than stock antennas.
What are the options for car radio antenna types?
The options for car radio antennas include internal car antennas, external car antennas, power antennas, and satellite antennas. The internal antenna is the least effective and most cars come with either the external fixed antenna or the power antenna unless their is a satellite radio in the car and then it is a satellite antenna.

If antenna is passive than how can it add gain?
Antennas provide so called passive gain, which means it comes from particular shape of the antennaThe gain of an antenna is a passive phenomenon - power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna. If an antenna has a gain greater than one in some directions, it must have a gain less than one in other directions, since energy is conserved by the antenna.SOURCE: wikipedia.com
What is the definition of regime?
The definition of regime is a mode or system of rule or government: a dictatorial regime.It's when somebody or Several people take control over a land or several areas and lands and gain power of them
What is gain of typical TV FM vhf only home antenna?
The actual numbers are not as important as the knowledge that generally speaking, the larger the antenna the more gain it will have. Three other main factors are the Distance from the transmitting antennas are from your location and the Height of your antenna above the ground and what Obstructions there might be between the two antennas.
What is a Decibel power gain?
Generally power is expressed in watts. The gain is the ratio of the output power to the input power. Gain = (output power)/(input power) if the gain is expressed in terms of log(base10) it is known as Decibel power gain Decibel power gain = Log10(Gain)dB if 1milliwatt power is taken as reference then Decibel power gain = Log10(Output power/1 milliwatt)dBm
Definition of the word acquire?
The definition of acquire means to gain possession, to have, or to get.
