6 kV Ring Wave Surge Withstand All ports withstand multiple 6 kV ring wave surges per IEEE specification C62.41 Category A3. -45 dBmV Spurious and Harmonics after 5 Surges of 6 kV Ring Wave with a +55 dBmV Return Signal Proprietary ferrite blend inhibits re-magnetization of the core due to voltage spikes from impulse noise or lightning. The ferrite remains ultra linear to prevent intermodulation where high level return carriers can affect forward path video signals. Digital Broadcast and HDTV Ready Compatible with existing and future networks. Flat 1 GHz Bandwidth with Minimal Insertion Loss Supports present and future multimedia applications including video, data and telephony. High Return Path Output Return Loss and Port-to-Port Return Band Isolation Excellent return path performance compatible with two-way digitally modulated networks.
