The V2TH and V4TH Satellite Antennas provide a cost-effective, high-performance geostationary satellite data telemetry link for hydrological and meteorological data transmission. Stevens’ V2TH and V4TH helix design virtually eliminates all existing problems that occur with other available antenna technology. The antennas are designed to operate through the destructive forces of severe weather, including extreme freezing temperatures, hurricane-force winds and immersion in the snow of mountainous regions.

Apart from physical size, the primary functional difference between the V2TH and V4TH Satellite Antenna is the gain ( V2TH is 5.5 dB Nominal, V4TH is +10 dB Nominal). Also, when pointed directly at a satellite, the V4TH antenna’s input power range of 6.5 to 10 watts (6 to 25 watts for the V2TH) results in the GOES DCSpermitted EIRP of 48 to 50 dBm (44 to 50 dBm for the V2TH).
The Stevens V2TH and V4TH can be suspended or mounted inside nonmetallic protective structures, or mounted outside on a building, post or tower. For adjustable exterior mounting, the customers may use the Stevens Antenna Elevation Mount. The Elevation Mount has a universal design for use with either the V2TH or V4TH antennas, allowing them to be attached to a vertical pole using either U-bolts (2” provided), straps or hose clamps. The Elevation Mount can also be attached to a wall or other flat surface.
