The BT-380W is a voltage-switched dual-polarized C-band LNB that uses a 14/19V voltage output from a satellite TV receiver to the LNB to implement a satellite TV signal that receives horizontally polarized or vertically polarized waves.
Compared with mechanically changing the polarization direction (such as the adjustment of polarization with a motor), it has the advantages of simple feed structure, convenient installation and debugging.
At the same time, it is equipped with a two-ring feed and has passed the testing and certification of the national designated agency.
