Hot answer to chilled satellite problems

9 September 2016

Showcasing its latest systems to help satellite earth stations maintain uptime in winter climates, Walton De-Ice is featuring gas and electric heaters and controls for antenna protection.

The company’s newest CE-approved heaters have been combined with updated automated control features to offer improved efficiency for satellite broadcast facilities.

Walton’s Hot Air De-Ice systems, including the company’s Plenum enclosure installed on the rear of antennas from 3.7m to 32m in diameter, are claimed to provide the most reliable and economic antenna de-icing solutions on the market.

Walton said that its Hot Air De-Ice systems heat the entire antenna reflector uniformly, which minimises reflector distortion that can cause signal problems, especially at Ku- and Ka-Band.

Also at IBC is Walton’s Ice Quake system, which vibrates and sheds snow and rain off antenna covers from 0.6m to 6.3m in size, preventing snow and ice build-up.

The company claims that Ice Quake can save broadcasters up to 100 times on energy costs compared to competing anti-ice systems, and that money is also saved by avoiding the need for high power conduit, trenching and switchgear.

Ice Quake uses an RF-transparent Walton Snow Shield antenna cover made of rugged architectural fabric.
