LNC مخفف Lon Noise Convertor است که برای تقسیم بندی سیگنال های فرکانسی به دسته های low/vertical ، low horizental ، hi/vertical ، hi/horizental استفاده میشود .The function of the Low Noise Converter (LNC), which is sometimes also called an LNB (Low Noise Block converter), is to:amplify the very low level incoming signals up to a level that can be demodulated by the satellite receiver.frequency translate the incoming signals to a lower frequency. It is more efficient to operate at a lower frequency because practical transmission lines have high cable losses at 4 GHz and especially at 12 GHz. The band that is conventionally used for transmission from the LNC to the satellite receiver is 950-1450 MHz.Power for the LNCs active components is typically 12-15VDC applied between the inner and outer of the coax cable that connects the LNC to feed to the satellite receiver.In addition to bringing the incoming signals to a suit اجرای خدمات نصب آنتن مرکزی در اصفهان...
