2. Effective radiated power - Wikipedia

   en.wikipedia.org/wiki/Effective_radiated_power

   It is equal to the power input to the transmitter's antenna multiplied by the isotropic antenna gain = The ERP and EIRP are also often expressed in decibels (dB). The input power in decibels is usually calculated with comparison to a reference level of one watt (W): P in ( d B W ) = 10 log ⁡ P in {\displaystyle P_{\text{in}}\mathrm {(dBW ...

3. Gain (antenna) - Wikipedia

   en.wikipedia.org/wiki/Gain_(antenna)

   A transmitting antenna is supplied with power by a transmission line connecting the antenna to a radio transmitter. The power accepted by the antenna is the power supplied to the antenna's terminals. Losses prior to the antenna terminals are accounted for by separate impedance mismatch factors which are therefore not included in the calculation ...

4. Antenna measurement - Wikipedia

   en.wikipedia.org/wiki/Antenna_measurement

   The first technique developed was the far-field range, where the antenna under test (AUT) is placed in the far-field of a range antenna. Due to the size required to create a far-field range for large antennas, near-field techniques were developed, which allow the measurement of the field on a distance close to the antenna (typically 3 to 10 ...

5. Noise temperature (antenna) - Wikipedia

   en.wikipedia.org/wiki/Noise_temperature_(antenna)

   and is the logarithmic gain of the antenna in decibels. The antenna noise temperature depends on antenna coupling to all noise sources in its environment as well as on noise generated within the antenna. That is, in a directional antenna, the portion of the noise source that the antenna's main and side lobes intersect contribute proportionally.

   The Cimple TV Antenna Amplifier is a powerful distribution amplifier with an adjustable gain feature that reaches up to 24 decibels. Simply turn the adjustment knob to the amount of gain needed ...

7. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   Outdoor antennas provide up to a 15 dB gain in signal strength and 15-20 dB greater rejection of ghost signals in analog TV. [6] Combined with a signal increase of 14 dB due to height and 11 dB due to lack of attenuating building walls, an outdoor antenna can result in a signal strength increase of up to 40 dB at the TV receiver.
