Anything drawing up to 30W at the port under IEEE 802.3at — which covers the great majority of Wi-Fi 6/6E/7 access points (Ubiquiti U6 and U7, TP-Link EAP, Netgear WAX and similar), 4K PoE IP cameras, and VoIP handsets. Lower-power 802.3af devices at 15.4W are supported too. Devices requiring 802.3bt PoE++ are not; for those, look at the KB-M3-04.

No. G.hn data occupies 2–200 MHz while the TV pass-through port carries 250–2150 MHz, so satellite TV and DVB-T2 sit entirely above the data band. An integrated diplexer keeps the two separated on the same cable — no lost channels and no external filter needed.

No. DOCSIS upstream starts at 5 MHz and overlaps the G.hn band directly. If you have cable internet, put the modem right at the point of entry and use the KB-G3-03 only on the inside-home wiring beyond it — or choose the KB-M3-03 MoCA 2.5 + PoE+, which runs in D-Band and coexists with DOCSIS by design.

Yes — a coax network needs a device at each end, which is why the KB-G3-03 ships as a two-adapter kit. You can add more later: up to 16 adapters can share a single coax network.

1.6 Gbps is the physical layer rate on a clean coax path, and iperf testing on our bench reaches it consistently. Real-world results depend on your cabling: keep total loss across the path under about 35 dB, use wideband splitters rated 5–1000 MHz, and avoid amplifiers that block the low band.

Yes. Both are ITU-T G.hn Wave 2 devices on the same 2–200 MHz plan, so they pair and interoperate normally. A common setup is a KB-G3-01 next to the router and a KB-G3-03 at the far end where PoE is needed.

Hold the PAIR button on the first adapter for three seconds until its LED blinks, then do the same on each additional adapter within two minutes. When every PAIR LED is solid green the network is encrypted with 128-bit AES. Holding PAIR for six seconds clears the security setting again without touching your IP configuration.

Usually, though it depends on the building. Modern blocks with isolated coax per unit work perfectly. Older buildings on a shared trunk may see reduced throughput, and you should enable AES pairing so neighbouring equipment cannot join your network.

Yes — that is a common deployment. When placing an adapter at the internet entry point ahead of the router, disable its DHCP client in the web interface and assign a static management address, so it does not compete for your ISP’s public IP.

Yes. Enable IGMP snooping in the multicast section of the web interface and multicast IPTV streams pass through correctly.

Coax is a shielded, purpose-built transmission line; mains wiring is neither. In practice that means roughly 1.6 Gbps versus 500–1000 Mbps, sub-millisecond latency instead of variable latency, and immunity to the motor noise and circuit-breaker boundaries that cripple powerline links.

30-day returns through Amazon and a 1-year limited hardware warranty. If the G.hn LED stays dark, check the coax connection first, then try a different outlet. For anything else, email info@kiwee-broadband.com.
