Its specified 100 kHz to 30 MHz operating range defines the applicable signal bandwidth. The 14 dB +\/- 0.5 dB tap loss and maximum 0.8 dB trunk insertion loss characterize the signal attenuation introduced by the tap connection.\u003c\/p\u003e\n\u003cp\u003eThe drop and trunk paths are electrically isolated according to the supplied specifications.
