Solid Signal is an Authorized Reseller of King Controls products.
Works with all models of DIRECTV and Dish Network satellite dishes. Adds a protective layer to overcome satellite signal loss due to rain, dew, and snow forming on the dish and LNB surfaces.


  • Single can of Dome Magic should coat a standard size DIRECTV or Dish Network satellite dish 3-4 times

  • Single application of Dome Magic should last 6-12 months depending on exposure to the elements

  • Most effectively used when applied to both LNB and dish surface area

  • Works best when applied in temperatures between 60° and 110°F

  • Protective Rain Shield coat prevents rain, dew, and snow from collecting on dish surfaces

  • Rain Shield is developed by the manufacturers of SeaKing and KingDome in-motion satellite reception systems for use in marine and recreational vehicle applications

  • We can not ship to Puerto Rico or Hawaii due to Aerosol Shipping Regulations

  • Compatible with all DirecTV and Dish Network satellite dishs. Not intended strictly for domes and can be used on any satellite dish.


Satellite Signal Rain Fade - Causes & Explanations
Even the most reliable satellite communications technology can sometimes be out-matched by the forces of nature. It’s a phenomenon known as “rain fade” or “rain attenuation” – a weakening of the satellite signal as it passes through raindrops.
Rain fade is one of the most common, and often most misunderstood, phenomena to affect satellite signals. But the more you learn about the causes of rain fade, the better your chances are to lessen its impact on your satellite system. Rain-fade is not service provider dependant, DIRECTV and Dish Network equipment are equally susceptable to the effects of signal loss due to rain-fade. 
The Causes of Satellite Rain Fade
Any satellite communications system network operator using a Ku-Band system (12/14 GHz or higher frequencies) will face the effects of rain fade at some time. But to understand why this weakening occurs with Ku-Band transmissions, you must first understand the causes of satellite rain fade. Two of the most common causes are listed below.
Absorption – Part or all of the energy generated when a radio wave strikes a rain droplet. The droplet is converted to heat energy and absorbed by the droplet.
Scattering – A non-uniform transmission medium (the raindrops in the atmosphere) causes energy to be dispersed from its initial travel direction.
Scattering can be caused by either refraction or diffraction:
Refraction – The refractive index of the water droplets encountered by the radio wave.
Diffraction – the travel direction of the radio wave also changes as it propagates around the obstacle in its path (a water droplet). 
These different reactions ultimately have the same effect – they cause any satellite system to lose some of its normal signal level. Don’t expect to lose your satellite signal every time it rains, though. Rain outage will only occur during the heaviest rains (convective and stratiform are the most predominant types) with only a small portion of the transmission path experiencing attenuation. In fact, of a typical satellite transmission path measuring 22,300 miles, less than .02% will be affected by rain fade.
The Impact of Satellite Rain Fade
Rain rate is the most common factor used to determine rain fade. Rain fade seems to correlate very closely with the volume of raindrops (expressed in cubic wavelengths) along the path of propagation. This is opposed to the common misconception that the degree of attenuation is proportional to the quantity or individual size of the raindrops falling near the receive site.
Pinpointing the specific factor that lead to attenuation is essential to accurately predicting the problem. Models can be developed from this data to chart the effects of rain fade on a regional or individual site basis.

Use on my satellite dish. It kept the snow offdidnt lose signal.

While this site gives a (very technical) specifications description, that description does nothing to help one determine how the refraction, diffraction, absorption, etc., actually plays out on the surface of the intended receiver. Most "domes" are mobile, where the signal travels under certain weather conditions (wind being the predominant factor washing away the elements from the surface almost immed.).

However, a stationary receiver (dish) accepts the elements as is, and is dependent on its location, shielded or not, its height above a ground surface (terrain or roof), azimuth angle, and side-to-side movement (protected away from most storm directionals).

The LNB box requires more protection due to the acceptance of the signal and ultimate disbursement to the cable line. Yes, some of the intended signal will be lost due to wind, rain, snow, and ice--the signal itself akin to a laser beam. This product is like a can of non-stick PAM, but one will lose the signal regardless if one has four feet of snow, excessive wind causing dish jostling, rain or ice forming on the dish surface. All this product does is make the surface more responsive after a storm, dependant on the sun's heat or direction. One can't beat Mother Nature.
Dome Magic NOT for satellite dishes!
- Paradise, se CA -
I realize this product was marketed for satellite domes not dishes. They were right. I bought Dome Magic because Rain Fade was out of stock everywhere and because SOME websites said Dome Magic worked well for satellite dishes. It does not keep snow from sticking to a Dish Network satellite dish. I followed the application instructions exactly and snow almost seems to stick better than before the
