The Stevens V4TH and V2TH Satellite Antenna provides a cost effective, high performance geostationary satellite data telemetry link for hydrological and meteorological data transmissions. The helix design virtually eliminates all existing problems that occur with other available antenna technology. The V4TH and V2TH Antennas have a 10 dB gain and 5.5 dB gain, respectively. These antennas are designed to operate through the destructive forces of severe weather.
