How to Use a Satellite Dish Signal Meter

Updated February 21, 2017

A satellite dish signal meter has the sole purpose of measuring the signal strength of a satellite transmission being transferred from a LNB (low noise block amplifier) to a satellite receiver. The set-up procedure for the satellite dish signal meter is straightforward and does not require any previous experience. No tools are needed, although you'll need a single coaxial cable.

  1. Unscrew the coaxial cable connected to one of the LNB (low noise block amplifier) modules that are on the pole attached to the front of the satellite dish. Screw the coaxial cable into the "Receiver" or "Destination" coax output on the meter, depending upon the make of the meter.

  2. Turn the "Trim" knob on the meter counterclockwise until the needle is dialled back opposite "5" on the printed scale inside the meter's view panel.

  3. Screw an end of the coaxial cable into the coax input labelled "Ant" or "Source" on the meter (the name of the input will vary depending upon the make of the meter).

  4. Look at the needle in the viewing panel --- a number higher than 5 indicates a strong signal being sent by the LNB, while a number below 5 indicates a weak signal. No signal is being sent if the needle is hugging the 0 on the scale.

  5. Loosen the knobs controlling the elevation and lateral movements of the satellite dish one at a time. Slowly move the dish while viewing the meter to see whether you can increase the signal strength. Lock the knobs back down when you are done.

  6. Return the satellite dish to its normal operation by unscrewing the coaxial cable from the meter's coax input and from the LNB's coax output. Unscrew the coaxial cable from the meter's coax output and screw it back into the coax output of the LNB.

  7. Warning

    A digital satellite signal meter requires batteries in order to operate.
