Residential Digital Coaxial Amplifier 5-Port 1.2 Ghz Voip From Antronix, G2/Acp. The Antronix VoIP Residential Amplifier provides a passive VoIP port for reliable voice service, even when power is disrupted to the amplifier. The 5 output port amplifier has 4 amplified output ports with unity gain in the forward and return band plus one passive VoIP output port. This amplifier utilizes the Antronix patented CamPort. This auto-seizing F-port ensures maximum contact area and reliability for multimedia applications. The all-ports-down configuration allows for ease of installation in a NID enclosure and can be powered with a power inserter (included) Passive VoIP Port The passive VoIP port provides continual service, even when power is disrupted to maintain critical voice service Unity Gain Forward and Return Active gain in the forward and return band provides unity gain in both directions for ease of installation Low Intermodulation Ferrites Proprietary ferrite blend inhibits re-magnetization of the core due to voltage spikes from impulse noise or lightning. This prevents high-level return carriers from affecting forward path video signals 6 kV Surge Protection Unique surge protection on all RF ports without the use of arc gaps which may cause high impulse noise during discharge Power Inserter Included for Remote Powering The amplifier is optionally powered remotely with a dual isolation compartment power inserter for high AC to RF isolation to prevent ingress
