DIY TV Aerial Repairs: What You Can Fix and When to Call a Pro


At some point, most households will encounter some form of issue with their TV aerial, leading to poor reception or no signal at all. Understanding what you can safely and efficiently attempt to fix yourself, and recognising when it is time to call in a professional, can save you both time and money.

Assessing the Problem

The first step in tackling any aerial issue is proper diagnosis. Before climbing up to your roof, make sure that the problem indeed stems from the aerial and not from something more easily solvable, like improperly connected cables or issues with your TV set itself.

Common Symptoms of Aerial Problems

  • Loss of signal during poor weather conditions
  • Pixelation or freezing of TV channels
  • No signal message
  • Missing channels

Checking the Basics

  • Ensure all cables are properly connected and in good condition.
  • Re-tune your TV to search for all available channels.
  • Check if the issue persists on all TVs connected to the same aerial.

Common Aerial Issues You Can Fix

There are several minor problems with TV aerials that you can address on your own with a little bit of caution and the right tools.

Realigning Your TV Aerial

Occasionally, strong winds or heavy rain can cause the aerial to shift out of alignment. You can realign your aerial by loosening the mast slightly and rotating the aerial while checking the signal strength on your TV.

Replacing Damaged Cables

Weather and wear and tear can damage the cables connected to your aerial. Inspect the cables for any visible signs of damage. Replacing old or worn-out cables can sometimes resolve the issue.

Clear Obstructions

Sometimes, new obstructions like growing tree branches or new constructions can block your aerial’s line of sight to the transmitter.


Trimming trees or repositioning the aerial to a clearer view can enhance reception.

When to Call a Professional

While some issues are easily fixable, there are situations where calling a professional aerial installer or repair person is advisable to avoid risk or further damage.

Installing a New Aerial

If your current aerial is outdated or significantly damaged, it’s best to have a new one installed by a professional who can ensure optimal positioning and secure installation.

Structural Damage to the Roof or Aerial

If the aerial is visibly damaged or causing damage to your roof, it’s crucial to call in professionals who have the necessary equipment and training to handle the situation safely.

Persistent Reception Issues

If after all your adjustments the reception does not improve, the problem might be more complex, requiring specialised diagnostic tools and knowledge.

Complex Systems

Homes that have integrated systems, combining TV, internet, and satellite might require a professional to correctly diagnose and fix issues without disrupting the entire setup.

Tools and Safety Gear

Should you decide to undertake aerial repairs yourself, having the right tools and safety equipment is crucial.

Essential Tools

  • Adjustable wrench
  • Screwdrivers
  • Wire cutters

Safety Equipment

  • Sturdy ladder
  • Safety harness
  • Gloves and non-slip shoes

DIY Tips and Tricks

Here are a few tips to enhance your DIY aerial repair efforts:

  • Always check the weather forecast before planning repairs. Avoid high winds or rainy conditions.
  • Have someone assist you, ensuring that the ladder is stable while you are on the roof.
  • Regular maintenance such as checking and cleaning your aerial can prevent many issues.


DIY TV aerial repairs can be a rewarding challenge, offering an opportunity to learn more about how your system works. However, it is important to recognise the limits of what should be attempted on your own. For complex issues, installations, or when in doubt, it’s wise to contact a professional aerial installer. Regular maintenance and timely repairs can ensure that your TV reception remains clear and reliable, saving you from unnecessary disruptions and expenses.
