Newbie level 4
A lossless antenna with directive gain of 8 dBi is fed with a 2 W power. The total radiated power of the antenna will be:
i. 16 W
ii. 8 W
iii. 4 W
iv. 2 W
i. 16 W
ii. 8 W
iii. 4 W
iv. 2 W

Total radiated power wouldn't be total if excluding some directions, adding "all directions" once more can cost unclear further assumptions.The total radiated power in all directions
Given relative directive gain in one direction is 8 dBi. It is not a power gain expressed in dB. Omitting (i) is no good idea. It is not either possible to assume a power ratio ("db higher in one direction") relative any other directions as we not have information about these other directions, or better expressed as a radiation sphere surface area, where size of current 8dBi area compared to any else part of the sphere area is unknown (gain&area).peak power is 8dB higher in one direction
