Used only a few times on-site as a temporary measure. Operation has been confirmed, but please understand that this is a used item. This is a booster that amplifies CS/BS-IF and CATV signals, compatible with 4K8K satellite broadcasting (3224MHz). It is used to strengthen radio waves when the TV signal is weak or when it is necessary to send the TV signal to multiple TVs. This product has a high-shielding structure, making it less susceptible to and less likely to be affected by radio waves from Wi-Fi, mobile phones, professional radio, and amateur radio. Amplification Bandwidth: CATV Uplink 30dB, CATV Downlink 38dB, BS/CS 35/45dB. BL Excellent Housing Component Certified Product. [CATV・SH-1]. For indoor use.
