Teardown, Experiment: ST Gold (MTI) AP8-T2J & BAS 11300Mhz LNBs

An integral part of any satellite receiving system is the low-noise block downconverter (LNB), sometimes incorrectly called a “low-noise block”. As satellites use high frequencies of ~3-5Ghz for C-band and ~10-13Ghz for Ku-band transmissions and are very limited in transmission, … Continue reading
