It depends upon the type of antenna. For example, a Yagi antenna's gain can be increased by adding elements. A parabolic antenna's gain can be increased by increasing the diameter of the antenna. All antennas can have their gain increased by lowering the loss of the feed line. By replacing regular coaxial cable with nitrogen pressurized coax, the overall gain at the receiving end can be increased. Gain can also be increased by inserting an amplifier between the antenna and the receiver. Another method of increasing gain is to reduce the VSWR, or voltage standing wave ratio.
When determining the appropriate antenna size for a wireless communication system, factors to consider include the frequency of the signal, the distance the signal needs to travel, the desired coverage area, and any obstacles that may interfere with the signal. Additionally, the antenna's gain, polarization, and radiation pattern should also be taken into account to ensure optimal performance.
An antenna picks up waves by converting electromagnetic fields into electrical signals. When radio waves interact with the antenna, they induce an alternating current within the antenna which is then processed by the connected circuitry to extract information or energy from the waves. The size and shape of the antenna determine which frequencies it is most sensitive to.
Antennas pick up waves through a process called electromagnetic induction. When an electromagnetic wave passes through an antenna, it generates a small electrical current in the antenna which can be detected and amplified to recover information encoded in the wave. The size and shape of the antenna determine the types of waves it can efficiently pick up.
The factors affecting the operating point of a system include the input signal level, the system's gain or amplification factor, the system's biasing conditions, and any non-linearities in the system's components. These factors collectively determine the output behavior of the system at a specific operating point.
An antenna works by converting electrical signals into radio waves for transmission and vice versa for reception. When an electrical current flows through the antenna, it creates electromagnetic waves that can travel through the air. These waves carry information in the form of radio signals. The antenna's design and length determine the frequency of the radio waves it can send and receive.
an antenna with 0 gain. What you hear and transmit is what you get from your 2-way radio.
That depends on a number of factors. Antenna height both receive and transmit. Transmitter power and antenna gain. About 15 miles max.
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.
increases by 6 dB
The size of an antenna depends upon the frequecny of the RF signal and the gain.
The amplification factor Vout/Vin determines the voltage gain.
EIRP (Dbm)= Output Power(Dbm)-Losses(from cables & adapters)+Antenna Gain(Db)
Radar range is affected by various factors, including the transmitted power, beamwidth, frequency, propagation losses, and antenna gain. Antenna gain plays a crucial role in determining the effective range of a radar system, as it focuses the transmitted energy in a particular direction, increasing the signal strength in that direction and consequently extending the radar range. A higher antenna gain typically results in a longer radar range by improving the system's ability to detect and track targets at greater distances.

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

Gain in antenna propagation refers to the measure of the directionality and efficiency of an antenna in transmitting or receiving electromagnetic waves. It represents the ability of the antenna to focus its radiated power in a specific direction, usually compared to an isotropic radiator. A higher gain indicates a more focused radiation pattern and improved performance in that direction.
