When carrying the Internet connection In all rooms of the house, the ideal is to have a good “standard” installation based on Ethernet cables, but since it is not always possible to have it, the most common thing is that we use wireless systems with WiFi, which are simpler and faster to use.
We may also prefer to use a wired connection using the resources that we already have deployed and installed at home. To do this we can opt for the popular PLC adapters that use the home electrical network to send the information, or another less known option that is based on the use of classic coaxial cables.
Using the antenna cable to bring Internet to the rooms
Many current homes have some installation inside with which they manage to carry the television signal of DTT from the outdoor antenna to one or several rooms of the house using cables that cross the different spaces of the house and that were once deployed in stripes. Are coaxial type cableswhich have also been used by some telephone operators to bring Internet to our homes before fiber optics were imposed.
The idea is power take advantage of these cables, which often directly connect several rooms with the living room or living room to have one more physical medium on which to carry the Internet connection. And for this there are a series of products on the market. coaxial-Ethernet adapters that can create a local network without having to deploy new wiring, thus achieving a kind of point to point ethernet extender that reaches different rooms.
These adapters are usually small and compact devices with the size of a PLC and practically They do not offer configuration or management options. They just connect, plug into the electricity and voila, they should start performing their function.
There are models with different transmission capacities, the most common being those that are limited to one 100 Mbps Ethernet connection (which later in practice will synchronize at a lower speed due to losses) and that are focused on the installations of security cameras or equipment that does not require much bandwidth, although they are more than enough for the majority of activities that we ask of them, such as browsing. , play Full HD videos, play games, etc.
In addition, there are also more advanced models that promise higher synchronization speeds and data transmission with figures that surpass gigabit and that in some specific equipment they reach the 2.5Gbpsso they are recommended for intensive network uses when we frequently want to move large amounts of data.
What do I have to consider before buying one of these adapters?
The main drawback of these devices is that not all homes are prepared for them to work correctly, since we need direct coaxial wiring between the two ends of the network that we are going to create. If there are signal splitters, amplifiers and the like, something very typical to carry the TV signal to different areas of the house, the performance may decrease considerably or the we cannot directly establish the Ethernet network.
Therefore, before buying anything, it is advisable review what our installation is like and verify that between the rooms where we want to carry the signal we have direct wiring, without divisions or other intermediate equipment that could hinder the Ethernet network. And if necessary, if we can, it is advisable to remove these dividers to avoid signal losses.
You also have to think about the type of use of the adapter, since there are models specifically designed to transmit the signal from the IP security cameras which are cheaper but offer fewer features. If we want it for a cutting-edge Ethernet network we will have to look for an adapter focused on this type of use, something that will increase its price.
It is also advisable that we previously evaluate how many connectors will we need. There are models with a single coaxial socket on each adapter and others that allow several sockets to, for example, carry, in addition to the Ethernet signal, the television signal to the room simultaneously in case we want to continue having access to DTT throughout the house.
It is also common to include some interference filtering system from other services that may be using the same coaxial cable, such as the cable modems of some telephone operators. If we have one of these, it will be a good idea for us to have this type of filters.
Comtrend GCA-6000 Powerline
This model of Comtrend GCA-6000 It is one of the few “name brands” for sale and consists of a set of two devices that promise speeds of up to 1200Mbps. Each adapter has two coaxial jacks, one of them to maintain the TV signal, an Ethernet output and the power socket. Its price is 219 euros.

ScreenBeam Mocha 2.5
Another interesting option is this model of Screen Beam which promises to achieve synchronization speed of up to 2.5 Gbps, although then the Ethernet port is limited to 1 Gbps. It is a kit with everything you need, including two adapters, coaxial cables and Ethernet in case we need them. Its price is 294 euros.

GoCoax Moca 2.5 Adapter
Another option is this model GoCoax which also has a capacity of 2.5 Gbps synchronization and this time an Ethernet port at that speed. In this case it is an individual model, so we will need at least buy two identical to establish the network. Its price is 80 euros.
