#### 3.1.1 Broadband Tuner  
The MEASAT-3A satellite with vertical polarisation is swept, and the result is depicted in Figure 9. The FSS-ES with the phrase new C-band OFF at an 85 m distance denotes the signal intensity under clear sky conditions without GB, which is around \(-81.7\) dBm. The DL frequency of a C-band satellite is typically between 3.625 and 4.2 GHz, and the \begin{table}

The operator's 5G frequency allotment is between 3.4 and 3.5 GHz, whereas the frequency resources received by the Malaysian Communications and Multimedia Commission are between 3.5 and 3.6 GHz. The two frequencies are close to the C-band satellite signal frequency. When the signal travels through the LNB, the downconversion frequencies are 1.450 and 1.65 GHz.
