The SMT automatic precision design employs a processing method that suppresses antenna signal attenuation and noise. Precise frequency separation of terrestrial digital and BS/CS by WWC suppresses attenuation and noise of each broadcast. It has a triple-shield structure that is strong for receiving 4K8K broadcasts (frequency band ~3224MHz). Teflon wire is used to reduce noise and is strong for receiving conventional terrestrial digital broadcasts and BS/CS broadcasts. Discounts, returns, and exchanges are not accepted. Thank you.
