Trunk line socket (through socket) with low connection attenuation (average 8 dB), (corresponds to GUT 123) Inserts up to 862 MHz Inserts from ASTRO (designation in brackets) with socket (RF) and plug (TV) for connecting a sound radio receiver and a television receiver For coaxial cables with outer conductors up to 5.5mm o The antenna sockets are suitable for connection to - a terrestrial reception system, or - a BK connection The antenna sockets are return channel suitable for a frequency range from 4 MHz to 20 MHz. The antenna sockets are DBP-approved according to 1 R8- 15. In principle - spur line sockets only for star cabling - a trunk line socket with terminating resistor should be used at the end of a trunk line. Shielding level > 85 dB, corresponds to class A
