Antenna De-Ice Systems

Sustainability through Reliability

The formation of ice and snowfall, especially on parabolic antennas, is a major cause in loss of signal transmittal and reception during winter months or for dishes at high altitude locations.

With over seventeen (17) years in the industry, Surface Heating Systems Ltd have successfully developed a range of heating systems compatible with most major manufacturers antennas to prevent the build-up of snow & ice, keeping the antennas operational in the most severest of weather conditions and thus preventing interference and costly down time.

Heating systems can be constructed of either:

1) Alufoil – Specially shaped soft backed aluminium heating panels – which are applied direct to the convex side of the antenna and controlled via an ice/snow sensing control unit.

Alufoil systems installed have ranged from diameters of 0.5m up to (at present) 18m with power loadings to suit.

2) GRP/Plastic backed segments –This is a robost hard backed system which is attached to the rear of the antenna and can either, (depending on the antenna make) directly heat the antenna structure or via intermediate enclosed air gap.   Both variations are controlled via the snow/ice control unit.

GRP systems installed have ranged from diameters of 0.5m up to 3.7m with power loadings to suit.

Installations of smaller systems typically take a couple of hours to install, with the larger heating systems taking a matter of days to complete.   The majority of our systems can be installed whilst the antenna is online, therefore reducing costly downtime.

The systems are extremely flexible and can be easily tailored to suit the customer’s requirements and location parameters, enabling “1/3, 2/3, 3/3” or “1/2 and full heating”.  Systems can also come with remote access as an enhanced feature.

Controls and monitoring capabilities can also be designed and built to suit system performance and operational needs particulars such as country specific power ratings, loads and or project specific details can be easily accommodated.

There are numerous benefits for using an SHS system ‘Versus’ a conventional Hot Air system :

  • Competitive Pricing
  • Reduced lead times
  • Reduced Shipping dimensions and costs
  • Quicker installation times
  • Minimum moving parts resulting in less negligible breakdowns
  • Reduced power requirements
  • More effective controlled thermal footprint
  • Heat can be tailored to specific areas depending on snowfall conditions.
  • Fully automatic controls with remote monitoring

Our system designs encompass but are “Not Limited To” the following antenna manufacturers:-

  • ASC
  • Andrews
  • Channel master
  • D.H.
  • Elite
  • Prodelin
  • Prime Focus
  • Vertex
  • Viasat
  • Challenger

 KA band systems:

SHS in conjunction with Munich University have successfully tested Antenna De-Ice systems for operations within the KA Band sector.
