Receive Antenna
Receive Antenna General Description
2:27. The receive antenna is an array of four crossed loop antennas. Each of the antennas is comprised of
two loop antennas at right angles to each other. The Pre-amp / Polarization Switch mounted under the
crossed loop antenna then combines the signals from each of the two loops to receive lefthand or righthand
circularly polarized waves from overhead. Each crossed loop antenna occupies a square 1.2 meters x 1.2
meters (4 ft. x 4 ft.) and stands about 1.5 meters (6 ft.) high (see Figure 2-2).
