how to check signal strength

Checking your TV aerial signal strength is important to ensure you are receiving the best possible reception.

There are a few different ways to test aerial signal, and the most accurate way will vary depending on your location and setup.

Here are some tips to help you get the most accurate results.

How do I test my TV aerial signal strength?

If you want to know how strong your TV aerial signal is, you can use an aerial tester.

First, make sure that your TV is turned off. Then, connect the aerial tester to the aerial socket on the back of your TV.

Once the tester is connected, turn on your TV and switch it to channel 3. The signal levels will be displayed on the screen.

If the signal is strong, you will see a green light. If the signal is weak, you will see a red light. If the signal is very weak, you will see a yellow light.

How to check If the Issue comes from Your TV Or Cable?

If you don’t have strong signal quality on your television, there are a few things that you can do in order to check if the issue is coming from your TV or from your cable.

One thing that you can do is check the strength of your radio signal on another device, such as a computer or a phone. If the signal is strong on the other device, then the issue is likely with your TV.

Another thing that you can do is to move your TV to a different location in your home and see if the signal strength improves. If it does, then the issue is likely with your antenna cable.

If you have tried these things and you are still having problems, you should contact your cable company and they will be able to help you troubleshoot the issue.

What is a good aerial signal strength?

There are many factors that affect the quality of an aerial signal, and therefore its strength. 

In general, the taller the outdoor antenna, the better the signal. This is because it can broadcast its signal further and reach a larger area.

Additionally, the higher the antenna is, the less interference it will experience from objects on the ground, such as buildings and trees.

The type of antenna also affects signal strength. Directional antennas, which focus the signal in a specific direction, are more powerful than omnidirectional antennas, which broadcast the signal in all directions.

The surrounding terrain can also affect signal strength. If the antenna is located in a valley, for example, the signal will be weaker than if it were on a hilltop.

This is because the signal has to travel further to reach the broadcast tower, and it will be blocked by objects in the way, such as mountains.

Finally, any obstacles between the air antenna and the receiving station will weaken the signal. This includes things like trees, buildings, and even hills.

The further the signal has to travel, and the more obstacles it has to pass through, the weaker it will be.

How do I test an antenna with a multimeter?

If you’re in the market for a new antenna, you might be wondering how to test it with a multimeter.

A multimeter is a handy tool that can be used to test a variety of things, including electrical circuits and components.

While it’s not the only piece of equipment you’ll need to test an antenna, it can be a helpful part of the process.

There are a few different ways to test an antenna with a multimeter.

One way is to measure the impedance. This can be done by connecting the multimeter to the antenna input and measuring the voltage across the terminals. The impedance of an antenna is typically expressed in ohms.

Another way is to measure the capacitance. And that’s by connecting the multimeter and measuring the current through the terminals. Usually, it’s in Farads.

Finally, you can also use a multimeter to measure the inductance. It is typically expressed in Henries.

Once you’ve measured the impedance, capacitance, and inductance of the antenna, you can compare these values to the specifications of the antenna to see if it meets your needs.

If you’re looking for a specific type of antenna, you can use these values to help you narrow down your choices.

When you’re ready to purchase a new antenna, keep in mind that you’ll also need to take into account the size, shape, and location of this device.

With a little bit of research, you should be able to find the perfect antenna to fix poor TV reception.

How to check if a TV aerial is working?

If your TV picture is poor or keeps breaking up, there are a few things you can do to try to improve it. This advice applies to both indoor and outdoor TV aerials.

Step 1: Before you start

First, check that all the connections between your TV and aerial are secure and screwed in tightly. If you have a booster or amplifier, check that it’s plugged in and switched on.

If you have a satellite dish, make sure that it’s pointing in the right direction and that there’s nothing blocking the actual signal strength.

Step 2: Check for interference

Interference can affect the amounts of signal your TV receives, causing the picture to break up or pixelate.

If you live close to a transmitter, you may get some interference from other electronic equipment in your home, such as:

  • baby monitors
  • microwave ovens
  • halogen lamps
  • WiFi routers
  • cordless phones

To minimize interference, try the following:

  • move any interfering equipment away from your TV or aerial
  • disconnect any equipment you’re not using
  • plug your TV into the mains socket using a filter (this will help to block interference from your WiFi router)
  • if you have a satellite dish, make sure it’s not pointing at a reflector (such as a metal roof)

Step 3: Check the aerial cable

If you can see your aerial, check that the cable isn’t damaged or frayed. If it is, you’ll need to get a new cable.

If you have an old aerial, it may be time to upgrade to a new one.

Indoor aerials are less effective than outdoor aerials, so if you have an indoor aerial you may get a less annoying signal than the outdoor option.

If you’re not sure which type of aerial to get, you can use the TV aerial selector tool on the Freeview website to find out which aerial is best for your area.

Step 4: Get a professional to check your aerial

If you’ve tried all of the above and you’re still having problems with your TV signal, it’s a good idea to get a professional to check your aerial.

They’ll be able to tell you if your aerial needs to be repaired or replaced.


If you are having trouble with cable signal losses, be sure to check your aerial signal strength.

There are a few different ways to test it, and the most accurate way will vary depending on your location and setup.
