One of the most common misconceptions in Australian households is that the NBN and your TV antenna are connected. They are not. Your NBN connection delivers internet and phone services, while your TV antenna receives free-to-air television broadcasts over the airwaves.
They are two completely separate systems. However, there are some indirect ways the NBN rollout can affect your TV reception, and it is important to understand them.

NBN and TV Are Separate Systems
Your TV antenna picks up broadcast signals transmitted from towers operated by free-to-air networks. These signals travel through the air and are received by the antenna on your roof, then distributed through coaxial cabling to the TV points in your home.
The NBN, on the other hand, delivers data through fibre optic cable, fixed wireless, or satellite depending on your connection type. The two systems use different infrastructure and do not depend on each other.
When NBN Installation Affects Your Antenna
During NBN installation, technicians sometimes need to access areas where your existing antenna cabling runs, such as your roof cavity or internal wall spaces.
In some cases, antenna cables can be accidentally damaged, disconnected, or disturbed during the NBN installation process. If your TV reception deteriorated around the same time your NBN was installed, it is worth having an antenna technician check that nothing was knocked loose or damaged.
Good to Know
In rare cases, NBN equipment such as the NTD or modem/router can emit low-level radio frequency interference that affects nearby antenna cables or poorly shielded TV equipment. Try moving the modem away from your TV and antenna cabling if you notice issues.
Switching from Pay TV to Free-to-Air
Some households that previously relied on cable or satellite pay TV are now switching to free-to-air TV as those legacy services are phased out.
If your home has not had a working TV antenna for years, or if the old antenna was removed or left to deteriorate, you will need a new antenna installation to access free-to-air channels. This is a situation many Australian households are now finding themselves in.
Future-Proofing Your Home
Having both a reliable NBN connection and a properly installed TV antenna gives you the best of both worlds:
- →Fast internet for streaming, browsing, and working from home
- →Free-to-air TV for live news, sport, and entertainment that does not depend on your internet being up
- →Emergency broadcasting access even during internet outages
