Here we learn how to make a simple inexpensive satellite signal strength meter which can be used for aligning dish antennas with local satellites in order to achieve the correct positioning and maximum signal strength from the antenna.
The LNBs that are used for receiving satellite signals (digital or analogue) are designed to grab the entire group of available transponders from the relevant satellite rather than single specific channels.
Due to the high gain features that modern LNBs possess today, the above procedure is likely to induce a whole lot of RF energy into the connected receiver while the dish antenna is optimally aligned.
The proposed signal meter circuit is configured for measuring the magnitude of RF signals over an extensive frequency range by averaging out the overall energy received from all the transponders at once.
It is not recommended to adjust your Meostat dish through this circuit since the power output from this dish could be too low for the meter to detect anything significant and might create confusions.
