ScreenBeam ECB7250 vs goCoax MA2500D

For a new router-to-gaming-room connection, choose the ScreenBeam ECB7250 two-adapter starter kit: its guide documents the adapters, power supplies and patch leads for both ends. Choose goCoax MA2500D when extending compatible goCoax equipment or assembling your own pair after confirming the box contents; both models have one 2.5GbE port per adapter. Keep compatible installed MoCA equipment where possible, and settle provider/coax compatibility before ordering either.

The ScreenBeam starter guide establishes the kit inventory. The goCoax product page allows existing MoCA equipment to supply another endpoint, while warning about older-device compatibility.

Both makers specify up to 16 MoCA devices; goCoax explicitly says they share 2.5 Gbps of network capacity in its quick-start guide. Those figures describe the network, rather than a separate allocation for every room.

ScreenBeam ECB7250 vs goCoax MA2500D: the differences

Sources: ScreenBeam's kit guide, single guide and user manual; goCoax's model page and linked quick-start PDF.

ScreenBeam ECB7250: our pick for a fresh connection

The reason to choose ScreenBeam is the documented starter package. It supplies two adapters, two power adapters, two Ethernet cables, two coax cables and two coax splitters. That covers the basic connection between unused coax outlets; check lead lengths against your furniture and sockets.

Do not confuse the starter kit with the single add-on. ScreenBeam's separate add-on guide lists one adapter, one power adapter, one Ethernet cable and one coax cable, and explicitly excludes the splitter. Its user manual also describes a single adapter and a separately obtained splitter; that is a package difference from the kit guide, not evidence that the kit lacks splitters.

Also check the model: ScreenBeam's ECB6250 uses MoCA 2.5 too, but its Ethernet port is limited to 1 Gbps, according to the ECB7250 page's related-products section. “MoCA 2.5” alone does not identify the Ethernet port you want.

Check price on Amazon. Select the two-adapter starter package and verify its included-parts list before checkout.

goCoax MA2500D: choose it for an existing setup or a carefully counted pair

The MA2500D has one coax input, one 2.5GbE port, an MPS pairing button and wall/desk mounting options. goCoax distinguishes it from the older WF-803M, whose Ethernet port was gigabit. The MA2500D page supports the hardware comparison, without establishing the contents of every seller's package.

For a new link, order two MA2500D units, whether sold separately or explicitly bundled together. Confirm matching power supplies and included leads before adding extras: the quick-start guide calls for a 12V DC supply at each endpoint. ScreenBeam documents 5V DC, 2A, so keep each model with its own specified supply.

Availability affects the pick: goCoax's direct shop showed MA2500D out of stock when checked. Confirm availability before committing to this basket.

See the MA2500D at goCoax.

How many adapters and cables should you order?

These are calculated baskets for unused, connected coax outlets, with one Ethernet device per remote room. Counts include the router endpoint; each external adapter needs power, a coax lead and an Ethernet lead. ScreenBeam's connection guides and goCoax's network diagram establish that layout.

For the second row, buy the ScreenBeam starter kit plus one single add-on, or three MA2500D units. The router-side adapter serves the shared coax network; the additional room gets another endpoint. Reuse supplied or suitable installed leads before buying more.

A gateway's coax socket is insufficient evidence of a usable MoCA LAN bridge. goCoax's guide distinguishes Fios/Frontier MoCA WAN, which can conflict with its defaults, from a router's built-in MoCA LAN bridge. Check the exact gateway and service arrangement before subtracting the router-side adapter.

The gaming-PC and TV-room path

For this example, internet reaches the router separately and the connected home coax is private, without a live provider or television feed. The makers' guides connect router LAN to the source adapter and the destination adapter to an Ethernet device.

1. 1

   Router LAN → adapter A

   Connect Ethernet to the source adapter and power it with its specified supply.

2. 2

   Adapter A → connected coax → adapter B

   Connect each adapter to its room's coax outlet. The outlets must join the same coax system.

3. 3

   Adapter B → gaming PC or TV

   Connect the destination device by Ethernet and power the remote adapter.

4. 4

   PC and TV together → Ethernet switch

   Put a switch after adapter B, then connect both devices to the switch.

Both adapters have only one Ethernet port. For a wired PC and smart TV, our switch layout needs four Ethernet leads total: router-to-adapter, adapter-to-switch, switch-to-PC and switch-to-TV. The TP-Link TL-SG108S-M2 is an optional eight-port 2.5GbE switch with a supplied power adapter; reuse a suitable switch you already own.

The 2.5GbE port does not guarantee that speed through the whole connection. goCoax says the devices share MoCA capacity, and ScreenBeam says wiring condition, noise and attached Ethernet hardware affect throughput. We therefore give neither model a lower-ping award. For installation detail, see Ethernet backhaul setup; for alternatives to coax, see MoCA vs powerline.

Check the coax before buying accessories

Both models use the 1125–1675 MHz MoCA band. goCoax requires splitters that cover that band and warns about old 5–1002 MHz splitters. A cable-TV socket and a working television picture alone do not establish this path's suitability.

• Yes: Connected private coax with outlets in both rooms: the basic layout above
• Partly: Cable internet or cable TV on the same wiring: verify frequencies, splitters and provider topology
• Partly: Fios or Frontier with coax from ONT to router: check MoCA WAN conflicts before connecting
• No: DirecTV, Dish or other satellite TV on the same coax network
• Partly: Building-managed or shared apartment coax: get the wiring and isolation assessed first

goCoax allows a separate non-satellite coax network only if it shares no splitter or run with satellite TV. ScreenBeam also specifically excludes AT&T internet and U-verse coax networks; ask ScreenBeam about your specific service before choosing it.

Splitters and the complete accessory basket

If a coax outlet already feeds a set-top box, ScreenBeam calls for a two-way splitter. Its starter kit includes splitters, while its add-on does not. For a separately needed splitter, the Antronix MMC1002H-B is a two-way horizontal option: the current manufacturer datasheet explicitly supports MoCA 2.0 and 2.5 across 975–1675 MHz. Keep compatible installed splitters instead of replacing them automatically.

Sharing an outlet also changes the cable count. Wall-to-splitter, splitter-to-adapter and splitter-to-set-top-box means three coax leads at that outlet, including the existing television lead. The basic room-count table assumes no such sharing. ScreenBeam says a three-way splitter, excluded from the kit, is needed when two existing coax devices also occupy that outlet.

With an unused router-side outlet and one TV-shared remote outlet, that means four coax leads total. If the existing TV lead fits the new layout, keep it: the starter kit's two coax leads plus one additional coax jumper complete this example.

For longer Ethernet patch leads, the Cable Matters 160001 Cat6 pick uses bare-copper conductors and standard RJ45 connectors (maker specifications). Cable Matters' own variant table identifies the linked version as one black 7 ft cable; measure each route before choosing it. Check price on Amazon.

Management, encryption and keeping older adapters

Both makers document browser management and initially disabled MoCA encryption. Enable security using the exact model's instructions before relying on MPS pairing: ScreenBeam manual, goCoax guide. goCoax's interface can show link rates; these are diagnostic information, not an internet speed guarantee.

ScreenBeam lists backward compatibility with MoCA 2.0, 1.1 and 1.0. goCoax lists 2.0 and 1.1, with a warning about some older chipsets. Keep functioning compatible endpoints, but confirm mixed-model operation rather than assuming a replacement adapter upgrades every older endpoint's performance.

How we choose

We compared official product pages, package inventories, manuals and the current Antronix datasheet, and kept existing site product identities. The ScreenBeam recommendation follows from its documented kit contents; the goCoax alternative follows from its port specification and expansion guidance. Cable counts are arithmetic from the illustrated connections, not manufacturer bundle promises. Where the makers' pages conflict on filters, we show the disagreement. We have not physically evaluated either adapter. Our selection method explains the research approach.

Verdict

Buy the ScreenBeam ECB7250 starter kit for a fresh basic link. Add a MA2500D to a compatible existing goCoax setup, or build a confirmed two-unit order when available. Count endpoints, supplies and leads first; add splitters only where the wiring requires them, and settle shared-service compatibility before buying a filter.
