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.
