The transmitter was carried by a helicopter, on which a steerable helix antenna was mounted. The measurements were performed with a high resolution, pseudo random sequence based channel sounder with a chipping rate of 100 Mcps and 200 MHz bandwidth. The transmit antenna was right-hand circularly polarized (RHCP) while the receive antenna for the channel sounder case consisted of a set of patch antennas with two orthogonal linear polarizations covering a surface that approximates a semi-sphere.
