75 Ohm VoIP amplifier kit

This 75 Ohm VoIP integrated residential amplifier kit provides five output ports for distributing cable TV and broadband signals throughout a home. It includes a passive VoIP port that maintains critical voice service with a 4.5 dB loss even when amplifier power is disrupted. The all-ports-down configuration simplifies wiring inside a network interface device enclosure. The package ships new with an AC adaptor, power inserter, coaxial cable and ten RG-6 connectors.

Passive VoIP port with 4.5 dB loss

The single specification that decides suitability is the passive VoIP port, which guarantees 4.5 dB insertion loss and keeps telephone service active during a power outage. Four amplified outputs deliver unity gain in the forward band while the return path remains active for modem communication. Low-intermodulation ferrites resist core re-magnetisation from voltage spikes, and the patented CamPort F-connectors ensure reliable contact. A PTC-protected UL-listed adaptor and optional remote powering via the ARPI-2000 inserter complete the feature set.

Installers needing lifeline voice support

This kit suits professional installers and residential builders who require a lifeline-compliant voice port inside a NID enclosure and want all components — amplifier, power inserter, cable and connectors — in one box. It is not for buyers who need more than four amplified data outputs, who require a purely passive splitter without active amplification, or who must avoid any mains-powered device in the signal path.

Questions about this item

How does the 4.5 dB passive VoIP port keep phone service alive when the amplifier loses power?

The VoIP port is a passive 4.5 dB tap that stays connected to the coax line even if the amplifier loses AC power, so voice traffic passes through without amplification.

What does the 75 Ohm rating limit when connecting this amplifier to existing coax?

The 75 Ohm impedance matches standard residential RG-6 coax and F-connectors, preventing signal reflections that would degrade forward and return path performance.

What clearance does the all-ports-down design need inside a NID enclosure?

All five F-ports face downward, so the enclosure must allow enough vertical space below the unit for cables to bend cleanly without stressing the CamPort® auto-seizing connectors.
