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.
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 ...
