The Aaronia 282 Heavy-Duty Pistol Grip with Polarization Change Function is strongly recommended for the use of larger antennas like the HyperLOG 30xxx and 40xx series, as it can support antennas up to 6 kg. With a single push of a button, the plane of polarization can be set to 45 and 90 degrees, which greatly facilitates the measurement. The antenna is supported by a high-quality spring-head rotation in any direction. A grade display makes this a consistently reproducible alignment. With the quick release plate a fast exchange of multiple antennas is possible. The ball mount allows perfect orientation on a tripod stand (just press, adjust and release the pistol grip - finished). The tripod mount is available in 1/4 in. or 3/8 in. size, so mounting on all standard tripod pins is possible. The tripod also fits to all Aaronia Spectran Handheld Spectrum Analyzers.
