  Wouldn't be this (excerpts from the official guide, #2 and #4 I'm not as sure on): 1. Gain - In other words, the gain of an antenna is a measure of how effectively it can focus RF energy in a certain direction. 2. Radiation Patterns: Between 2 and 4 I was unsure for this one but the fact they spend a lot of time talking about graphing it, this felt best in #2. 3. Beamwidth: The beamwidth is determined by finding the strongest point on the plot, which is usually somewhere on the outer circle. Next, the plot is followed in either direction until the value decreases by 3 dB, indicating the point where the signal is one-half the strongest power. 4. Polarization: The electrical field wave’s orientation, with respect to the horizon, is called the antenna polarization.

  NM given answer correct, I mixed up #1 and 2 when I wrote the. The excerpts still fit though, just first radiation, gain, beam, polar
