NAB, LAS VEGAS,19 April 2016. Engineers at Alpha Satcom Inc. (ASI), a provider of satellite earth station antenna solutions in Longview, Texas, have selected systems from Walton De-Ice, designer and manufacturer of satellite earth station antenna (ESA) weather protection solutions in San Bernardino, California, for an installation at a major satellite broadcast facility.
ASI is designing, fabricating, and supplying a unique 9.0-meter Ku-Band low-passive intermodulation (PIM) antenna with challenging RF and structural design requirements for its customer; ASI engineers selected Walton De-Ice as part of the total solution.
Passive intermodulation (PIM) on antennas can disrupt networks by creating signal interference. Low–PIM antennas minimize this effect.
“The very nature of this type of system not only requires special RF and structural design but also extremely sensitive installation and operational constraints,” says Bill Anton, president/CEO of Alpha Satcom Inc. “We understand the critical needs of our customers to have high-performance, reliable systems that can receive and transmit a signal cost effectively under the harshest conditions. By thermally bathing the backup structure and panels in a homogeneous manner, the Walton De-icing will help support Low PIM operation for many years.”
Alpha Satcom Inc. (ASI), with headquarters in Longview, Texas, and facilities in China, provides a wide range of large satellite earth station antenna solutions in C-band, X-band, Ku-band, DBS, Ka-band, and hybrids for both commercial and military applications, including special requirements for performance in extreme environments.
Walton’s Hot Air De-Ice systems, including the company’s unique Plenum enclosure installed on the rear of an antenna, provide reliable and economic antenna de-icing solutions, offering maximum flexibility with electric, natural gas, and liquid propane gas heater options. Unlike other types of heaters, such as electric pad systems that can cause reflector distortion, Walton Hot Air De-Ice systems heat the entire antenna reflector uniformly, which minimizes reflector distortion that can cause signal problems, even more so at Ku-, and Ka-Band.
During the NAB Show 2016 in Las Vegas, April 18-21, 2016, at Booth OE504, Walton De-Ice will be promoting its latest in gas and electric heated hot-air Plenum systems for large antennas (3.7 to 32 meters), as well as its innovative Ice Quake, and Snow Shield solutions for 0.6 to 6.3 meter antennas.
For over 36 years, W.B. Walton Enterprises Inc., known as Walton De-ice, has designed and manufactured a broad, high-performance line of De-Ice equipment for satellite earth station antennas. From its original hot air (Plenum) design which mounts behind antennas from 3.7 to 32 meters, to its Snow Shield, Rain Quake, and Ice Quake, Walton De-Ice systems for 0.6 to 6.3 meter antennas, Walton De-Ice solutions help protect critical satellite networks from degradation and outages due to weather.
