! Field !! Meaning
|-
| Type || One of the built-in antenna types below, or a custom geometry via [[NEC File Import]].
|-
| Wire Length (m) || The main dimension. Its label adapts to the type (circumference for the loop, element length for the vertical, driven element for the Yagis). '''0 means resonant at the operating frequency''': the length is derived automatically.
|-
| Height (m) || Height of the feedpoint or apex above ground. Height strongly shapes the vertical radiation pattern of horizontal antennas: low antennas radiate upward (short range), high antennas radiate at low angles (long range).
|-
| Azimuth (°) || Orientation, 0 is north, 90 is east. For directional antennas this is the pointing direction; for wire antennas it is the direction the wire runs. Disabled for the vertical.
|-
| Feedline Loss (dB) || Fixed loss of the cable between transmitter and antenna. Subtracted from the radiated signal in both cases.
