Notation: x±y±z; x is the center frequency. If y appears, the center frequency is not sensed, but two bands, one on either side of the center frequency, are sensed; y is the distance from the center frequency to the center of the two pass bands. If z appears, it is the width of the two pass bands. This pattern is easily implemented with radio frequency receivers, and it effectively doubles the signal (two pass bands instead of one).

Polarization: V = vertical, H = horizontal, R = rotates with scan angle.
