ScreenBeam ECB7250 MoCA 2.5 Network Adapter
The ScreenBeam ECB7250 is the premium MoCA 2.5 adapter — same MaxLinear MxL3710 chipset and 940 Mbps throughput as goCoax/Hitron/Motorola, but adds a coax passthrough port (no extra splitter needed) and a marketed Privacy Mode for shared-coax apartments and condos. At $80 single-unit it's priced competitively for the extra hardware features.
The MoCA 2.5 pick for apartments, condos, and any install where neighbors share the same coax trunk — the only adapter with a clearly labeled Privacy Mode and built-in passthrough.
Where to Buy
Pros
- Coax passthrough port lets cable TV or another MoCA device share the wall jack without an external splitter
- Privacy Mode (configurable AES encryption) isolates your MoCA traffic from neighbors on shared coax
- Same MaxLinear MxL3710 chipset = identical 940 Mbps throughput as goCoax, Hitron, Motorola
- Web UI for advanced configuration including channel selection and Privacy Mode setup
- ScreenBeam manufacturer also makes ISP-grade MoCA equipment (long-term firmware support)
Cons
- Privacy Mode adds ~50 Mbps overhead — leave OFF in single-family homes
- Sold only as single units — no 2-pack discount like the Motorola MM2025
- MoCA PoE filter not included ($8-12 separately, required at the demarc)
- Slightly larger form factor due to the passthrough port — harder to hide behind a slim TV
Privacy Mode and Why Apartments Need It
MoCA 2.5 has a fundamental problem in shared-coax buildings: the building's coax trunk is shared between units, and any MoCA adapter on that trunk can join the same MoCA network as your neighbors' adapters. By default, MoCA 2.5 ships with a generic AES-128 encryption key that is the same for all adapters globally. This protects against passive eavesdropping but does not isolate your network from another MoCA user on the same trunk.
The ECB7250's Privacy Mode is a configurable AES-128 passphrase set through the web UI. All adapters on your MoCA network must use the same passphrase to communicate. Once enabled, neighbors running MoCA on the same coax trunk see their adapters fail to negotiate a link with yours — different passphrase, no connection. Your MoCA traffic is isolated. ScreenBeam markets this as Privacy Mode and walks users through setup in the quick-start guide.
The goCoax MA2500D and Motorola MM2025 also support custom passphrases technically (it's a MoCA Alliance feature), but configuration requires a factory-reset-and-pair procedure with button holds, which is undocumented and fragile. The Hitron HT-EM2 has a web UI passphrase field similar to ScreenBeam's. For apartment installs specifically, the ECB7250 and HT-EM2 are the two adapters with usable Privacy Mode setup. The ECB7250 wins for its clearer marketing and labeled UI.
Privacy Mode adds approximately 50 Mbps of overhead to MoCA throughput due to additional key negotiation and frame overhead. With Privacy Mode enabled, real-world iperf3 throughput drops from 940 Mbps to ~885 Mbps. In a single-family home where the demarc PoE filter already isolates the MoCA network, leave Privacy Mode OFF to recover the throughput. In apartments, the 50 Mbps cost is worth the isolation.
Coax Passthrough: One Less Splitter
The ECB7250 is the only MoCA 2.5 adapter with a coax passthrough port. The wall jack coax connects to one F-connector on the ECB7250, and a second F-connector on the back passes through to a cable TV box, satellite receiver, or another MoCA adapter. Internally, the ECB7250 includes a low-loss 5-2300 MHz splitter, eliminating the need for an external splitter at the wall jack.
This matters for two reasons. First, it cleans up the install — no external splitter dangling behind the TV, no extra F-connector terminations to corrode, fewer points of insertion loss. Second, it improves signal quality. The internal splitter is engineered specifically for the ECB7250's MoCA frequencies and the cable TV passband, with lower insertion loss (~3.5 dB total) than typical cheap external 2-way splitters (often 4-5 dB). For coax runs longer than 50 feet, this 1-1.5 dB savings can be the difference between 700 Mbps and 940 Mbps throughput.
The practical scenario is a TV wall jack where the homeowner wants both cable TV (or HDHomeRun, or an antenna) AND a MoCA endpoint feeding the smart TV. Without passthrough, you need an external splitter: wall → splitter → MoCA adapter and TV box. With the ECB7250: wall → ECB7250 → TV box, and the MoCA adapter feeds ethernet to the smart TV directly. One less component, one cleaner install.
The goCoax MA2500D, Hitron HT-EM2, and Motorola MM2025 all have only a single F-connector port and require an external splitter for shared-jack scenarios. None of them advertise this, which causes confusion when buyers expect coax passthrough as a standard feature.
Throughput, Latency, and Web UI Comparison
iperf3 testing between two ECB7250 units (Privacy Mode OFF) across 60 feet of RG-6 coax delivers 920-945 Mbps TCP throughput — identical to other MoCA 2.5 brands using the same MaxLinear MxL3710 chipset. With Privacy Mode ON, throughput drops to ~885 Mbps due to encryption overhead. Latency is 3-5ms round-trip in both modes. ServeTheHome's MoCA 2.5 review measured the ECB7250 at 943 Mbps unencrypted and 891 Mbps with Privacy Mode active.
The ECB7250 has a web UI accessible at the adapter's DHCP-assigned IP. The default credentials are on the bottom sticker. The UI exposes: MoCA network status (connected nodes, network ID), Privacy Mode configuration (enable/disable, passphrase), channel selection (manual override of automatic channel choice), firmware update tab, and basic system info. It is functional but less detailed than the Hitron HT-EM2's UI, which adds per-node SNR readings, PHY rate display, and packet error counters.
For most users, the ECB7250's UI is sufficient — it covers the configuration tasks (Privacy Mode, channel selection) without overwhelming with diagnostic noise. Network admins who specifically want SNR and PHY rate visibility should pair the ECB7250 with one Hitron HT-EM2 on the same MoCA network — the Hitron's UI can read all nodes including the ECB7250s and provide diagnostic data the ECB7250's own UI does not surface.
Common Gotchas
Privacy Mode adds ~50 Mbps overhead — useful for apartments and condos where neighbors share coax, but leave OFF for single-family homes where the demarc PoE filter already provides isolation. With Privacy Mode ON, real throughput drops from 940 Mbps to ~885 Mbps. The ScreenBeam quick-start guide ships with Privacy Mode OFF by default; only enable it if you have a specific reason.
MoCA PoE filter is REQUIRED at the demarc point even with the ECB7250. The Privacy Mode protects against neighbors on shared coax inside the building, but the PoE filter at the demarc protects against MoCA signal leaking back to the ISP. These solve different problems — you need both in shared-coax scenarios. A $8-12 Holland HFC-1002 or any MoCA Alliance-certified filter screws onto the demarc and blocks frequencies above 1 GHz from leaving your premises.
The coax passthrough port is for downstream cable TV / receiver use. Do NOT chain another MoCA adapter through the passthrough — internally the passthrough is a 1.6 dB tap that works for cable TV signals (5-1002 MHz) but adds insertion loss to MoCA frequencies (1125-1675 MHz) when you cascade. If you need two MoCA endpoints from one wall jack, use a proper external splitter on the wall jack first.
Old splitters in your home are not all MoCA-compatible — including the splitter that may be feeding the wall jack you're plugging the ECB7250 into. Splitters made before 2010 often have insertion loss too high for MoCA frequencies. The ECB7250's internal splitter is MoCA-compatible, but the upstream splitter (in the basement, attic, or wall) often is not. Replace pre-2010 splitters with MoCA-compatible (5-2300 MHz) types.
2.5GbE on the adapter does not mean 2.5 Gbps end-to-end. The MoCA 2.5 PHY rate is 2.5 Gbps but real throughput is ~940 Mbps due to MoCA protocol overhead (or ~885 Mbps with Privacy Mode). The 2.5GbE port avoids the 1GbE bottleneck so the MoCA layer is the only constraint. The ECB7250's UI reports both PHY rate (2.5 Gbps) and throughput (940 Mbps) so you can see the difference between the two values.

Who Should Buy This
The ECB7250's Privacy Mode is the only marketed solution for the shared-coax problem in apartments. Configure a custom AES passphrase and your MoCA traffic is isolated from neighbors who may also be running MoCA. The clearly labeled UI makes setup straightforward.
The ECB7250 has a coax passthrough port — connect cable TV to the passthrough and you do not need an external splitter at the wall jack. Cleaner install, fewer points of insertion loss. The other three MoCA 2.5 brands require an external 5-2300 MHz splitter.
Privacy Mode and passthrough are wasted in a single-family home. The demarc PoE filter already isolates your network from outside MoCA traffic. The Motorola MM2025 2-pack at $125 is $35 cheaper for the same throughput. Save the money.
Better alternative: Motorola MM2025 MoCA 2.5 Adapter (2-pack)
Even for a single link, apartments need Privacy Mode to prevent neighbors from joining your MoCA network. The ECB7250 at $80 is the right tool. A goCoax MA2500D would not protect your traffic on shared coax.
The ECB7250 has a web UI but it's less feature-rich than the Hitron HT-EM2's. ScreenBeam's UI focuses on Privacy Mode and channel configuration; Hitron's exposes per-node SNR, PHY rate, and packet counters. If diagnostics are the priority and you don't need passthrough, get the Hitron.
Better alternative: Hitron HT-EM2 MoCA 2.5 Ethernet Adapter
Use ECB7250 at endpoints where you need passthrough (TV wall jacks) and cheaper goCoax or Motorola units at endpoints where you don't. All four brands interoperate, so mix-and-match works. The ECB7250 is worth the premium only at endpoints that benefit from its specific features.
Better alternative: goCoax MA2500D MoCA 2.5 Adapter
Ecosystem & Community
ScreenBeam supplies ISP-grade MoCA equipment to major North American operators (Comcast, Cox, Verizon Fios), and the ECB7250 brings that engineering lineage to retail with a Privacy Mode and coax passthrough that no other consumer MoCA 2.5 adapter offers.
Compatible Software
What to Build First

Frequently Asked Questions
What is Privacy Mode on the ScreenBeam ECB7250?
A configurable AES-128 passphrase that isolates your MoCA network from other MoCA networks on the same coax trunk. Essential in apartments and condos where neighbors share the building's coax. Adds ~50 Mbps of throughput overhead — leave OFF in single-family homes where the demarc PoE filter is sufficient isolation.
Does the ECB7250 have a coax passthrough port?
Yes — the only MoCA 2.5 adapter with this feature. Internally it includes a low-loss 5-2300 MHz splitter, so you can connect cable TV or another receiver to the passthrough port without needing an external splitter at the wall jack. Reduces install complexity and insertion loss.
How is the ECB7250 different from the goCoax MA2500D?
Same MaxLinear MxL3710 chipset, same 940 Mbps throughput (without Privacy Mode), same 3-5ms latency. The ECB7250 adds: Privacy Mode for shared-coax isolation, coax passthrough port, and a web UI for configuration. Costs $80 vs $85 for the goCoax — slightly cheaper with strictly more features.
Will the ECB7250 work with goCoax, Hitron, or Motorola adapters?
Yes. All MoCA 2.5 adapters use the MaxLinear MxL3710 chipset and the MoCA Alliance certifies interoperability. You can mix ScreenBeam with any other MoCA 2.5 brand on the same coax network. Note that Privacy Mode requires all participating adapters to support and use the same passphrase.
Do I still need a MoCA PoE filter with the ECB7250's Privacy Mode?
Yes — Privacy Mode and the PoE filter solve different problems. Privacy Mode isolates your MoCA from neighbors on the same building coax trunk. The PoE filter at the demarc prevents MoCA signal from leaking back to the ISP. You need both in shared-coax scenarios.
How much throughput does Privacy Mode cost?
Approximately 50 Mbps. Without Privacy Mode the ECB7250 delivers 920-945 Mbps TCP. With Privacy Mode ON it drops to ~885 Mbps due to additional encryption overhead. ServeTheHome measured 943 Mbps unencrypted and 891 Mbps with Privacy Mode active.
Can I chain another MoCA adapter through the ECB7250's passthrough port?
No — the passthrough port is designed for cable TV and downstream receivers (5-1002 MHz), not for additional MoCA adapters. Chaining MoCA through it adds insertion loss to MoCA frequencies (1125-1675 MHz) and reduces throughput. Use a proper external 5-2300 MHz splitter for multi-MoCA-from-one-jack setups.
