It’s a weekend evening, and you sit down to watch TV, and Channel 7 is completely clear. When you flick over to Channel 9 for news, you find that the screen has frozen and it’s breaking up, and then suddenly disappears completely. The weather is completely fine; no thunderstorms, nothing. Then why is your TV antenna not getting all channels even though the antenna is working?
Quick answer: If your TV antenna is getting some channels not working but not others, it’s most likely a signal strength issue, not the antenna failing. The probable reasons behind such TV antenna signal issues are corroded cabling or an issue with the antenna’s positioning. A manual retune from mySwitch can help you to understand whether you are facing a tuning problem or you need to call out a technician.
About 99% of Australian houses install free-to-air TV; among these, 59% do this through broadcast antennas. So, don’t worry; there isn’t anything unusual in your setup; missing TV channels are very common.
One Weak Frequency and Your Entire Channels Get Disrupted
Like analogue TVs, digital ones don’t fade over time. If the signal quality at its frequency declines below its threshold, the channel suddenly disappears. Conversely, with a stronger neighbouring frequency, it keeps playing flawlessly. That’s the reason behind losing one particular network while you can watch others without any flicker.
What Are the Actual Reasons for Some Channels’ Drop-Out
Corroded Cabling
Connectors that are partially corroded can pass strong signals but lose fragile ones.
Misaligned antenna
The antenna can shift just one or two degrees off due to roof movement, wind, or loose brackets, weakening one or two frequencies. According to the Australian Communications and Media Authority, antennas last about 10 to 15 years, and misalignment is one of the leading reasons behind their potential decline.
Overloaded mobile tower
Mobile tower overload is often within a kilometer when you run a signal booster.
Overloaded signal dividers
If you are running more than one TV with a single antenna without an appropriate distribution, it can tip the weakest channels below the level.
Things You Need To Consider Before Consulting a Technician
First, you need to try a manual retune via mySwitch. If you found that a splitter is feeding multiple TVs, test one signal connection directly from the antenna. If you still face the same issue after a few days, that’s a physical issue. That’s where Fix TV Antenna’s signal-strength testing helps to confirm exactly what is causing this.
