Ice/Rain Quake

Protect your Ka-Band antenna from Snow, Ice, Rain, and the Sun

One cover does it all! With a PTFE Snow Shield Cover, you will have the protection of the Solar Cover System, Rain Quake System, and the Ice Quake System.


The Solar Cover will keep the temperature within the cavity the same as the outside temperature to help reduce the movement of the reflective surface during day light hours. 


Hundreds of Ice Quake Systems have been sold since being released into our product line in 2009.

DP-7IQ De-Ice Remote Monitor/Control Unit

The DP-7IQ is mounted on a 1.75” X 19” standard, single rack mount panel. The black powder finish assures high indicator visibility, even from a long distance. Termination of the cabling from the local unit is easily made through the rear mounted terminal blocks on the back of the unit. All connections to the unit are clearly marked on the rear of the panel to simplify installation. A de-pluggable terminal block for interface also makes swap-out a snap. Control Leads going to the DS-4C Local Control/Sensor are opto-isolated in order to improve noise immunity, reduce ground loop problems, and provide circuit protection. This also allows the DP-7IQ to be mounted up to 1200 feet away from the Local (DS-4C) Control/Sensor. Dry contact I/O and an optional Ethernet port for customer monitor and control equipment is also provided for monitoring the status of the deicing system along with allowing full remote Manual On activation, no matter what position the DP-7IQ control Switch is in. A panel indicator will show a remote M&C Manual On command.


Key Features:


  • Inexpensive Assurance of Proper De-icing Operation
  • Full Remote Control for Testing
  • M & C Interface for Station Control/Monitor by serial or Ethernet connection
  • 100-120VAC Standard, 200-240 VAC Optional
  • Controls can be located up to 1200 Feet from the Local Antenna De-ice Controls
  • Standard or High Density Configurations Available


The DP-7IQ remote control/status display panels coupled with the DS-4 provides a low cost method to remotely monitor and control your Ice Quake System. The DP-7IQ provides basic Ice Quake on Status for the Ice Quake System, along with Manual on, Automatic, and Standby control capabilities. The DP-7IQ also has a Feed Heater On Indicator.

Ice Quake Ka-Band | Rain Fade Testing

Rain Fade Testing of the Walton Snow Shield (Winterization Kit) Cover and Ice Quake System on a 3.9 meter Ka Band Antenna


Rain fade test performed at Ka Band using a FDMA Modem and a satellite simulator. The duration of each test segment was 10 minutes. Walton's solar-winterization cover, Solar Cover was combined with an activated Ice Quake System to assess signal performance withstanding water at a rate of 2.5 gallons per minute. During this phase of the test a total of 4 hits (data lost) were recorded (see photo). Testing was performed using a 3.9 meter GD antenna (see photo).

Summary of Testing Performed

Ice Quake's Electric Motor

The new Micro Series represents the natural evolution of the previous series produced by Italvibras. Experience acquired throughout years of work and specific workshop tests, have allowed significant improvements to be applied to both the technical aspects and design of the new Micro vibrators, so much so that the product has become even more reliable.

The Micro Series has been designed for continuous use in industrial processes that require smaller size electric vibrators with lower centrifugal force. Micro electric vibrators feature IP65 mechanical protection, a highly resistant light aluminum alloy casing and stainless steel weight covers.


Lubrication is not required as long lie maintenance-free type bearings are used.


  1. Weight covers in stainless steel that combine high mechanical strength with the protection guaranteed by stainless steel.
  2. Aluminum casing with surface polishing treatment.
  3. The fixing center-distances, which are identical to those of the previous Micro series, ensures perfect interchangeability.
  4. Stator insulated by means of the impregnation process, guaranteeing perfect insulation and the utmost protection against damage from the vibration process
  5. Ball bearings set in specifically researched positions to ensure top-most efficiency throughout the stress caused by the centrifugal force.
  6. The windings are subjected to the strict tests established by the standards in all pieces produced under CE, UL and CSA guidelines.
  7. The layered eccentric weights can be regulated in steps by changing the actual number of weights mounted.

Rain Quake

Minimize the Impact of Ka-Band Rain Fade

Walton Rain Quake systems reduce rain fade on your Ka-Band antennas, and protect your antenna G/T performance. During heavy rain conditions, Walton Rain Quake systems can reduce data loss — by over 20X compared to Ka-Band antennas without protection.


  • Prevents water from sheeting on your antenna surface - and causing Ka or Ku-band rain fade — from VSATs to large antennas.
  • Covers your antenna — keeping rain off with PTFE material that’s virtually invisible to RF.
  • Rain Quake is also the Ice Quake De-Icing System for year-round protection in areas with snow and ice.

Boosts Antenna Performance in Rain

Tests show that the Rain Quake System helps to minimize bit error rates and antenna noise temperature increases, as well as increase your link margins during a rain storm.
