How to Improve Radio Reception in a Metal Building – A Complete Guide

Radio is a device that is quite familiar to us when listening to programs and CDs. However, we will feel uncomfortable when the radio picks up the signal too slowly. Especially for metal houses, the ability to absorb radio waves is weaker.

So is there a way to increase radio reception in metal houses?

The answer is yes. In this article we will show you how to improve radio reception in a metal building.

If you want to learn more details, refer to the following article!

In a Metal Building, Why Do You Need to Increase Radio Reception

In large buildings, radio reception is often less effective than outdoors. Because the radio wave has to pass through the walls, glass, and metal in the house, the radio signal will be quite weak.

In addition, a home with a lot of metal furniture will have poor signal reception because the materials will prevent radio waves from reaching your radio.

Furthermore, radio waves are not stable. The strength of the wave will depend on many factors, such as the weather of your place. If your radio is in a metal house plus bad weather, good reception is very difficult.

In particular, metal houses far from the base station receive weaker signals. Therefore, to boost radio signal in a building is essential.

What Preparations Do You Need to Improve Radio Reception


In fact, you can apply a lot of ways to increase radio signal reception. In general, the method is not too difficult, and you can completely do it at home.

Even if you don’t have much radio expertise, you can still do it through the instructions below.

To make the process easy and fast, you need to prepare some necessary tools as follows:

  • A cable to connect the radio to the antenna.
  • An antenna: You can make use of old TV antennas.

What Can Be the Best Way to Improve Radio Reception

With the above preparations, this article will show you how to increase radio reception by using an outdoor antenna, which is a familiar device to many people. According to our research, using outdoor antennas provides the best reception efficiency and comes with many advantages.

After you have prepared the necessary tools, you need to check out the following steps:

Step 1: Find where to place the antenna

If the antenna is not installed, you need to choose the highest position where it is easy to set up. In addition, this location should not be blocked by many obstacles along the path to the signal source.

Conversely, if your home’s TV antenna is already installed in the right location, you don’t need to do this step.

Step 2: Connect the radio to the antenna with a cable

Next, choose a cable with a length equivalent to the distance from the radio to the antenna location. Then use one end of the cable to connect it to the radio receiver. The other end will be connected to the antenna.

Step 3: Detect signal coming from the broadcasting station

After the above steps, the signal detection step is the most important.

First, you turn on the radio. At this time, you may hear a very faint sound because the radio has not received the signal.

After that, point the antenna’s tip towards the base station and slowly rotate its head until the radio picks up the signal and emits a sound.

Step 4: Securely fix the antenna

Once you’re sure the radio has received a signal, keep the antenna in that direction and start fixing it tightly. Make sure the antenna can’t change direction when it’s windy or rainy.

Now you have an extremely effective radio receiver for your metal building. We are sure with the above steps, you can completely increase the reception of your home radio without much cost.

Other Ways to Improve Radio Reception


If you find the outdoor antenna installation too difficult, we recommend that you use an indoor signal antenna.

In this way, you prepare an indoor antenna that connects directly to the radio. This device is available at any store that sells receivers.

To avoid buying the wrong product, you can refer to several reputable equipment manufacturers such as Terk & Audiovox. Or more simply, you should go to the store and ask the staff for additional advice according to your needs.


Usually, the indoor antenna will operate on the principle of amplifying the signal that the station broadcasts.

Accordingly, the signal will be boosted by the indoor antenna before being received into your radio. From there, the ability to absorb radio waves will be more effective.

Of course, a small fact is that most radios already have a pre-amplification system in place. Therefore, you can choose a dipole antenna without a pre-amplifier instead.

Note that the antenna should be perpendicular to the line to the radio station to receive signals easier.


The antenna set in the network brings convenience and efficiency; you can easily buy them at the store. In addition, the indoor antenna is very suitable for small radios and does not require a lot of work.

Some Notes on Radio Reception

Of course, installing a receiver support device will help the radio’s signal speed be stronger. However, many factors around you influence the efficiency of radio reception. To learn more about this issue, let’s go to the section below.

Tips for stronger radio reception

  • Choose a suitable place to place the radio: put it in a high place, and where there are not many obstacles around. In particular, do not place the radio near materials such as metal.
  • Battery: Paying attention to the battery level is very important for radios. When the battery is almost empty, you must replace it in time to avoid affecting the reception and the quality of the radio.
  • Extend the antenna while tuning the radio. Although your home may have assistive equipment, do not forget to raise the radio antenna to increase reception.

Mistakes cause poor radio reception.

Besides tips to help increase reception, knowing the mistakes while using is extremely necessary. Here are the mistakes you can make that make radio reception weaker:

  • In addition, placing the radio too close to phones, televisions, or devices with electromagnetic wave levels will also affect its reception.
  • An antenna that has been affected by corrosion can cause interference.
  • Water damage of the antenna and the coax cable can also diminish the signal strength.

Currently, manufacturers produce many types of radios that can absorb signals well. They even use advanced technologies and do not need antennas to get radio reception in a metal building.

If you have a high demand for radios and love modern equipment, you can refer to these devices at major stores.


In short, increasing the absorption of radio waves in metal houses is extremely necessary. We hope this article showed you how to improve radio reception in a metal building, thereby giving you a more wonderful feeling when listening to the radio.
