The Sat Buddy from Applied Instruments is a basic satellite meter that measures relative RF signal strength when connected to a dish antenna. Use the Sat Buddy to align your dish antenna to obtain maximum signal strength. You can also use your Sat Buddy to verify signal presence within the in house cabling network. You can also power the LNB from the IRD set-top box through the Sat Buddy, or from the Sat Buddy's internal battery.
