The type of HF head that can be installed in the satellite cauldron depends on the size of the satellite cauldron, the receiving frequency range, and the type of satellite signal to be received. In general, the common types of satellite caldron HF heads include C-band HF heads, Ku-band HF heads, and Ka-band HF heads. The C-band high-frequency head is used to receive C-band satellite signals, the Ku-band high-frequency head is used to receive Ku-band satellite signals, and the Ka-band high-frequency head is used to receive Ka-band satellite signals. Different types of satellite cauldron can be compatible with different types of high-frequency head, the user should choose the appropriate satellite cauldron and high-frequency head according to the actual needs.
The satellite cauldron is generally not equipped with a high-frequency head, but with a low noise block (LNB), the role of the low noise block (LNB) is to amplify the weak signal of the satellite downlink and frequency conversion, in order to facilitate further processing and transmission.
The high-frequency head is generally used to receive terrestrial television signals, and the signal received by the satellite cauldron is a high-frequency microwave signal, so there is no need for a high-frequency head.
