They amplify the signal actively
Study Notes
Antenna Attributes
- EIRP (Equivalent Isotropically Radiated Power) is a measure of the equivalent power that would be radiated by an isotropic antenna in a certain direction.
- Isotropic antennas radiate power uniformly in all directions and have a gain of 0 dBi, which is a reference point for comparing the gain of other antennas.
- Not all antennas amplify the signal; some antennas are passive, meaning they only redirect or focus the signal without amplifying it.
- An antenna with 0 dBi is not faulty, but rather, it is a reference point indicating that the antenna has the same gain as an isotropic antenna.
Test your understanding of antenna basics, including EIRP, isotropic antennas, and antenna gain. Identify the correct statements about antenna characteristics and performance.
