Coax Networking Guide
Short answer: not with standard MoCA. Standard MoCA 2.5 adapters use the D-band (above 1 GHz), which sits inside the 950–2150 MHz range that satellite TV uses on your coax, so the two interfere. In a DIRECTV or DISH home, use a G.hn Wave 2 coax adapter (2–200 MHz, up to 1.6 Gbps) or an extended E-band MoCA adapter (400–900 MHz, up to 2.5 Gbps) instead.
Key takeaways
- Satellite TV uses about 950–2150 MHz on the coax; standard D-band MoCA overlaps it.
- G.hn Wave 2 (2–200 MHz) is the safest choice and works alongside DIRECTV Genie and DISH Hopper systems.
- Extended E-band MoCA (400–900 MHz) is faster, but can overlap DIRECTV’s own DECA network (about 475–625 MHz).
- Kiwee options: KB-G3-01 and KB-G3-03 (G.hn), KB-M3-02E (E-band MoCA 2.5).
Why standard MoCA and satellite TV don’t mix
The dish on your roof converts the satellite signal down to a range of roughly 950–2150 MHz and sends it over the coax to your receivers. Standard MoCA 2.5 adapters use the D-band, which sits above 1 GHz, right inside that satellite range. Put the two on the same cable and they interfere: you can lose channels, and the MoCA link becomes slow or unstable.
Second catch: many satellite systems already run their own network over the coax so receivers can share recordings. DIRECTV’s whole-home network (DECA) is itself a MoCA network, in roughly the 475–625 MHz range, and DISH Hopper and Joey receivers also talk to each other over the coax. Any adapter you add must stay clear of those signals too.
Option 1: G.hn over coax (the safest choice)
G.hn Wave 2 works at about 2–200 MHz, far below both the satellite signal and the receivers’ own home network. It delivers up to 1.6 Gbps with very low latency, and Kiwee G.hn adapters have a TV pass-through port (250–2150 MHz) with a built-in diplexer, so your receiver keeps its signal while the adapter carries your data on the same outlet.
G.hn Wave 2 · 2.5GbE
KB-G3-01
Up to 1.6 Gbps over coax for a PC, console, NAS or mesh node, with TV pass-through.
G.hn Wave 2 · PoE+
KB-G3-03
The same link plus PoE+ (up to 30W at the port) to power a Wi-Fi access point or camera.
One limit: G.hn shares its frequency range with cable internet (DOCSIS) and with some over-the-air VHF channels and FM radio. That rarely matters in a satellite home, but if you also have a cable modem or an antenna on the same coax, ask us first.
Option 2: extended E-band MoCA
MoCA can also run lower on the cable, in the extended E-band (about 400–900 MHz), below the satellite signal. This is the fastest coax option for a satellite home.
MoCA 2.5 · E-band · 2× 2.5GbE
KB-M3-02E
Up to 2.5 Gbps with two 2.5GbE ports, running below the satellite band.
Check first: the E-band can overlap a satellite system’s own home network. A DIRECTV Genie system using DECA, for example, already occupies part of it. If your receivers share recordings over the coax, or you are not sure, choose G.hn, or email us and we will check your setup.
Which adapter should you pick for satellite TV?
| Your situation | Best choice |
|---|---|
| Satellite TV, receivers linked over coax (DIRECTV Genie, DISH Hopper/Joey) | G.hn: KB-G3-01 or KB-G3-03 |
| Satellite TV, single receiver, no whole-home network | Extended E-band MoCA (KB-M3-02E) for top speed, or G.hn |
| You need to power an access point or camera | G.hn with PoE+: KB-G3-03 |
| Satellite cancelled, coax now unused | Once the dish equipment is removed and the satellite splitters are replaced with MoCA-rated ones, standard D-band MoCA (KB-M3-02) is the fastest |
How to set up Ethernet over coax in a satellite home
- Place the first adapter near your router. It needs a coax outlet connected to the same coax network as the rooms you want to reach.
- Keep the receiver on the TV pass-through port. Where an adapter shares an outlet with a satellite receiver, connect the wall to the adapter’s coax input and the receiver to its TV port, so both keep working.
- Don’t remove satellite parts you don’t understand. Multiswitches, SWM splitters and power inserters feed the dish. Leave them in place and work around them.
- Use the same technology on every adapter. G.hn adapters don’t talk to MoCA adapters, and E-band MoCA doesn’t talk to D-band MoCA.
- Turn on encryption. Pair the adapters with their push button so the network is encrypted.
Frequently asked questions
Can I use regular MoCA adapters with DIRECTV?
Standard D-band MoCA adapters overlap the satellite signal and are not recommended. DIRECTV’s own DECA adapters run an older, slower MoCA network for the receivers. For your own Ethernet network, use G.hn.
Does MoCA work with DISH Hopper?
Standard D-band MoCA is not recommended with DISH, because it overlaps the satellite signal on the coax. Hopper and Joey receivers also talk to each other over the coax. G.hn adapters, which run at 2–200 MHz, are the safest way to add Ethernet over the same cable.
Will a G.hn adapter affect my satellite picture?
No. Its data sits at 2–200 MHz, far below the satellite signal, and the TV port passes the satellite signal through.
How fast is Ethernet over coax in a satellite home?
Up to 1.6 Gbps with G.hn Wave 2, or up to 2.5 Gbps with extended E-band MoCA 2.5. Both are well beyond what most Wi-Fi delivers through walls and floors.
