Jung BSD21-10 2-Hole Hyper-Broadband Loop-Through Socket 10 dB

In modern TV and satellite distribution systems, a weak or poorly shielded antenna socket can cause signal loss, interference, and unreliable reception across multiple outlets. The Jung BSD21-10 2-Hole Hyper-Broadband Loop-Through Socket solves this by providing a dedicated 10 dB tap-off for TV and radio, while passing the full signal to the next socket with minimal loss. Its metal chassis and high shielding effectiveness ensure clean signal distribution in residential and commercial installations.

Who is it for

This socket is intended for electricians and installers setting up or upgrading antenna distribution networks in homes, apartments, and offices. It is suitable for systems carrying terrestrial TV, cable TV, and satellite IF signals, and works with DVB-T, DVB-C, and DVB-S receivers.

Main features

• Two outlets: TV (IEC male) and radio (IEC female)
• 10 dB tap loss for local connection
• Low loop-through loss: 1.5 dB (5-470 MHz), 2.0 dB (470-862 MHz), 2.5 dB (950-2400 MHz)
• Wide frequency range: 5-862 MHz for TV, 87.5-108 MHz for radio, 950-2400 MHz for SAT loop-through
• DC pass-through for satellite remote power
• 75 Ohm impedance
• Metal chassis for durability and shielding
• Flush-mount installation
