Yes, Antennas concentrate the signal into certain patterns compared to a model antenna. So the energy from the areas they don’t cover, they use at covered ares and therefore they “amplify” the signal. Calculation is as follows: 20dBm -2dB +4dBi -69dB +4dBi -2dB = -45dBm
Can somebody explain why C and not B? When antenna receives traffic it does not amplify the signal, does it?
