Pass4sure 640-722 Question Answer

If an antenna has a dBd of 8.6, what is the dBi value?

A. 6.2
B. 6.46
C. 8.6
D. 10.74
E. 12.88

Answer: D


Which calculation computes the EIRP of an antenna? 

A. EIRP = Tx power (dBm) + Antenna Gain (dBi) - Cable Loss (dB)
B. EIRP= Cable Loss (dB)+ Antenna Gain (dBi) - Tx power (dBm)
C. EIRP = Cable Loss (dB)+ Antenna Gain (dBi) / Tx power (dBm)
D. EIRP = Tx power (dBm) + Antenna Gain (dBi) / Cable Loss (dB)
E. EIRP = Antenna Gain (dBi) - Cable Loss (dB) * Tx power (dBm) F. EIRP = Tx power (dBm) * Antenna Gain (dBi) / Cable Loss (dB)
