Common TV Antenna Installation Issues (and How to Avoid Them)
At Jim’s Antennas, we’re often called in to fix TV reception problems—and more often than not, the issue comes down to how the antenna was installed. Here are some of the most common problems we come across and why it pays to call an expert the first time.
DIY Disasters and Dodgy Installs
We see a surprising number of DIY antenna jobs, as well as installs done by people who aren’t actually specialists. It’s easy to spot—antennas pointing the wrong way, poor-quality cabling, damaged roof tiles, and signal issues caused by incorrect setup. Unlike plumbing or electrical work, antenna installations aren’t regulated in Australia, which means just about anyone can give it a go. But for reliable TV reception, you need an expert who knows what they’re doing.
Outdated Antennas Still in Use
Even though Australia switched to digital TV in 2013, plenty of homes are still using old analogue antennas. While some might still pick up a signal, they’re prone to failure. If your antenna is more than 10 years old—or you’re constantly battling signal issues—it might be time for an upgrade. At Jim’s Antennas our experts can tell you whether a repair will do or if a modern digital antenna is the better option.
Faulty or Old Coaxial Cable
Not all reception issues start with the antenna itself. Sometimes the problem is in the cable that connects your antenna to the TV. Over time, coaxial cables can degrade, leading to weak signals or interference. In some cases, pests like rodents can even chew through the cabling. At Jim’s Antennas our experts will isolate the issue and let you know if replacing the cable is all that’s needed.
Weak Mounting or Loose Fixings
A securely mounted antenna should be able to withstand storms, strong winds, and even the odd possum. But many DIY installs don’t hold up under pressure. If your antenna moves in the wind or has already fallen over, it’s likely not been installed securely. At Jim’s Antennas our technicians will ensure your antenna is firmly fixed and weatherproofed for your local climate.
Misuse of Signal Amplifiers
Amplifiers can boost your TV signal—but only if you actually need one. Installing an amplifier unnecessarily or using the wrong strength can make reception issues worse. We’ve seen plenty of installs where someone has used an amplifier to try and “patch” a problem that really needed a better antenna position or newer cabling. Always ask for an explanation before agreeing to any extras.
Poorly Installed TV Wall Mounts
TV wall mounts are another common headache. We’ve fixed mounts that were the wrong size, installed at the wrong height, or simply unsafe. If your TV isn’t mounted into a wall stud, it could fall—posing a serious safety risk. Whether you’re installing a new TV or fixing an old setup, a professional will ensure it’s secure and suited to your space.
Not Enough TV Wall Points
Modern families often want TVs in multiple rooms—but many homes only come with one or two wall points. Whether you’ve got a growing family or want to watch TV in your home office or outdoor area, adding extra wall points can make your antenna setup more flexible and functional.
