What is the dBi value? 12/19/2016 – by Admin_VCEguide 0 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 SHOW ANSWERSCorrect Answer: D Explanation/Reference: Explanation: Antenna performance is measured in dBi (the antennas gain/loss over a theoretical isotropic antenna) dBd (the antennasgain/loss over a dipole antenna) dBi = dBd + 2.15 dBd = dBi – 2.15
