Antennas play an important role in radio communications. Increasing the height of an antenna can increase its range and gain up to 6 dB of gain. However, this amount of gain depends on the specific situation. Generally, the higher an antenna is, the larger its coverage area. The ground can interfere with horizontal antennas and mask or shield the signal. Therefore, it is important to choose an antenna that is higher than the ground.

The efficiency of an antenna is determined by looking at its radiation power versus its input power. The radiation efficiency is also referred to as the power gain ratio. The radiation power from the antenna is the sum of the input power and the power lost during the process of radiation. Antenna efficiency can be measured using different methods. Some measures account for losses due to the dielectric, I2R, and coupling to other devices. However, it does not take into account the mismatch loss, which happens when the antenna and transmission line do not match in resistance. Other measures factor in the change in radiation resistance. While most small antennas are not very efficient, those with between fifty and sixty percent efficiency are considered good.

Antennas are used in wireless communication, such as for mobile phones. While the wavelength of a radio signal determines the length of an antenna, it is possible to use half-wavelength antennas as well. These antennas are also known as quarter-wavelength antennas. However, in some cases, a quarter-wavelength antenna will do. Antennas are essential for wireless communications, and without them, it would be difficult to use mobile phones or televisions.
