What capability do most satellite signal meters have to evaluate the antenna dish and LNB?

The capability to power the LNB (Low Noise Block converter) is an essential function of satellite signal meters. This feature allows the signal meter to supply the necessary voltage to the LNB, which is crucial for receiving the satellite signal. The LNB converts the signals from the satellite into a lower frequency that can be processed by the receiver. By providing power to the LNB, the signal meter enables the technician or user to evaluate the performance of the whole system, including testing the signal strength and quality effectively.

While satellite signal meters can often measure satellite signal strength and aid in aligning the dish, these functionalities are secondary to the fundamental requirement of powering the LNB during testing and installation. Thus, ensuring the LNB receives power helps confirm that the system is operational and that the signal can be effectively processed.
