Thank you for viewing. This product is a DX Antenna CW40MSG2 TV booster. We ordered a large quantity, so it is a new, unused item. The items were delivered in packaging of 5 units, so there are no individual cardboard boxes. When shipping, we will wrap the item in bubble wrap and then place it in a cardboard box. This is a booster that amplifies CS/BS-IF and CATV, supporting 4K8K satellite broadcasting (3224MHz) and CATV (962MHz) in both directions. 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 that is resistant to and does not easily affect radio waves from Wi-Fi, mobile phones, professional radio, and amateur radio. It uses a die-cast chassis for high heat dissipation. Amplification band/gain: CATV uplink 36dB, CATV downlink 42dB, BS/CS 38/48dB. JEITA HS mark certified. For indoor use.
