Use these satellite signal meters to align your DirecTV or Dish Network satellite dish. The dish must be aligned when installed and periodically re-aligned. A strong wind might move the dish slightly off-center, or temperature extremes can cause the mounting hardware to warp.
When you "peak" your dish, you make sure that the strongest signal gets to your satellite box, reducing pixilation, picture freezes, and "Searching For Satellite" messages.
All of our meters work with DirecTV systems. Some (specified in the description) also work with Dish Network.
Both the dish and the meter need power to operate. All meters will work when connected in-line between the satellite receiver and the satellite dish because the receiver provides the power. Some meters (specified in the description) have their own power supply (plug-in or battery) that provides the power. In this case, no receiver is required to align the dish.
Only experienced installers should try to align a dish without a receiver. This feature is more often used when performing a "site survey"; Walking around carrying a dish and meter to different locations on a property to see where a signal can be received.
Why not use the signal meter built-into the receiver? Go ahead and try. The lag time is so great with those meters that a great deal of patience is required...and a patient helper watching the TV screen and yelling a series of numbers up to you on the roof.
