What is in an antenna on the radio?
Today, many radio devices are there that receive the signal coming from the station towers without fail. But, when you get an antenna in place, you can see how it makes a difference.
You will see there is less interference in the signal. That is great as it will help you to enjoy music better without any noise. Not just that, it even allows catching weaker signals that radio without an antenna might have missed out on for sure.
That’s why many radio enthusiasts are looking to know how to improve FM signal on the radio with a single wire antenna in place. And if you’re one of them, then today, you will get quick insight, how the antenna makes a difference in radio performance.
So, let’s not wait and get on the subject right away.
Single Wire Antenna: What It Is And How It Works?
Just like the name suggests, it is a single wire antenna. There is nothing but a bit of wire hanging out the device working as an antenna to get the radio reception. Making adjustments to this straight wire, you get all the things done. It is as simple as that. There is nothing much to it.
Ok, you’ve got that. Now comes the part where you might think how does this entire thing work? It isn’t that hard to understand either on the surface. Don’t go beneath the surface and just remember that, signals get transmitted, and the single wire antenna catches those signals roaming in the air to let you listen to them.
When it is time for it to transmit, the same thing happens, this time the other way around where a specific signal gets transmitted using the antenna of your device on the air. This is the process.
So, looking at it, you can see that a size of antenna can make a difference in terms of listening to those frequencies big time. The longer the antenna, the better the reception, that’s what is being said. And it is nothing but the truth in most cases.
However, for getting better reception with your FM radio, it seems like the 15-inches mark is more than enough.
Make Your FM Antenna Using Speaking Wire:
If you’re interested in making your own antenna out of speaking wire, then this is something that might interest you a lot. Let’s check it out.
PART ONE: Making the FM antenna:
The first step involves getting the right wire size. Get a 10 feet speaker cable and measure about 3 feet from that wire first.
The next thing you need to do is split that length (3-foots you’ve taken earlier) into two. Then all you need is to make a T-shape using those split parts. So, get them upright on opposite sides of each other like the letter “T” where the 3-foot split part makes the top and the remaining wire makes the bottom part of the letter.
The last bit of work that remains is on the long cable part that remains untouched before this. What you will need to do is strip the outer layer of insulation and just get the conductor of the wire out of the end part of it around 2-inches. That’s it.
PART TWO: Connecting to receiver
You’ve done making the antenna structure. Now, it is time to connect the antenna to the radio receiver to get it working. To do that, all you need is to locate the external antenna connection port or plug, whatever you’ve got on the radio. Usually, it can be find in the rear end of the device. And you will see some labels on the area like “ant” or “ext.ant”.
At the post of the external antenna connection make connection using the bottom part of the conductors that you’ve ripped out of the insulation cover. After doing that, you start wrapping around the cable wires. On some clamp-and-hold devices, you’ve got to do just that while making the connection.
Now, keep on twisting the wires together to turn it into one single wire. If it isn’t a single post or clamp external antenna connection, then this is something that you can avoid. And no worries, there is no risk of getting shocked doing the twisting the wire as no current runs through them.
PART THREE: Extending the range
Now comes the part, after getting the connection on the radio, you start working to get an improved range for better reception. The first thing you can do for that is place the receiver closer to a place like a window to get better signal reception. If you place the stereo itself in such an area, alongside the wire antenna, that might make some difference in reception quality too.
You’ve got a long single wire antenna. Use the length and get it out of the window for catching the wavelengths on it.
For the last part, adjust the wire out there in a particular location after doing some try and error to find the best reception point. Make sure, the wire remains there in the position using a nail or any other thing that might keep it there. Do the same for the separated wires to give them support too.
PART FOUR: Moment Of Truth
This is the part where you check whether all the hard work you’ve put in results in something or just got wasted. Just turn the receiver on and check the signal level on the stations you want to listen to.
If you don’t see the reception to improve, you can take your radio and place it somewhere else where you might get a better signal. If still there is no improvement, then you can add more wire to the extended T leads to improve the reception.
Ok, you’ve your antenna to improve the reception.
How to Customize a Single Wire Antenna for Improved FM Signal?
Using a single wire antenna, you can improve the signal. But you require a bit of customization.
How do you do that? That’s exactly what we will look into here.
To start the process, first, you need to disconnect the antenna on your radio. So, simply plug out the antenna from the port in the rear section of the device.
Now, from the antenna terminal, you will need to get the screws loosed on the rear area to remove the wire on the tuner too. Unscrewing the bolts, you will get the wire removed from its place quite easily. Get the antenna untangled from the wire. This will allow elevating it higher which is always better for getting better reception.
That’s a simple tweak you can make on the radio antenna to improve the reception quality on the radio.
You’ve got the antenna removed from the radio. Now, what you need to do is reconnect it again on the device. Then turn the radio on and try to tune into any station you like. As you’ve got an untangled antenna at your disposal, you need to extend it as high as you can to find the best reception point for it. In a conducive environment with a long antenna, you can move it around the space to see how the reception changes in a different position. Move it around on your hand to see the changes in quality. And if possible, get out on the rooftop or if you’ve got an attic on your house, go up there to get the peak position within the area. Doing this, you will ultimately find a spot where the signal strength the radio receives is better than most areas within your home.
You can’t hold on to the antenna forever. So, just take some tape out and stick the antenna of yours on to something for the time being. Right that moment, when you get your hands off the antenna wire, the signal starts to get weaker. That is quite common. No worries, just again move the antenna around to find a different position to get the best reception without you holding the thing.
Now, take the radio, and start moving with it in the room. Check if the signal deteriorates or has some interference of any sort while you do that. Depending on that, you’ve got to make the adjustments. When you’re sure of an area where you get the best reception, no matter your movement or the antenna being mounted without you touching it, that’s the spot where you need to permanently secure it.
To do that, get nails or screws rather than using the tape as it might come off when the adhesive gets weaker on it. Don’t forget about it.
Is it worth it?
The answer depends on you. If you can see, the tools to make the entire process complete aren’t at all expensive. Without spending a lot of bucks, you can get the stuff from the local hardware store.
In terms of time is where you need to think about whether the whole DIY customization will make it worth and spending those few bucks for the tool. If you love to work with gears like your radio, then you will find it quite fun to do.
And if you know your way around the single wire antenna, then it won’t take more than an hour. So, if you’ve got the time and money and a few bucks to spend, then no doubt it will be worth it, once you get to enjoy the quality reception on the FM radio yours.
Tricks To Boost The Signal:
To make all the hard work worth it, I’ve got some tricks up my sleeve that you can try to boost the FM signal.
Here they are:
- It is a simple but quite effective idea. Just have a long extension cord on the radio. This will then allow you to move it around to get better reception for sure.
- Make sure while doing so, you’ve got the stereo in the Mono
- Then you slowly and steadily increase the single wire antenna height and move it around at different angles to get better reception. Don’t haste with the process. The slower the movement, the better your chance to get the proper reception vantage point.
- While doing that, take your radio and place it near the window or any open that is close to the wavelength. If you can, have the window open as there will be fewer barriers in front of the radio. That might improve the chance of getting enhanced reception.
- Still, if you’re looking to boost the signal, then get a dipole antenna and plug it in the FM section of the radio.
- If you’re living in a rural area, then having an external antenna can make the difference as the transmission tower from your place is way further. To get those weak signals, that is quite crucial.
- Got that antenna placed on the roof or outside your home, then get the wire and connect it to the radio just like you’ve done so far with the rest of the antennas.
Hopefully, doing all that will improve the signal on the FM radio big time.
People Also Ask:
How can I improve my FM signal on a single wire antenna?
I’ve talked about it in detail in the above sections, but to sum it up, just get a longer wire antenna and try out a couple of positions before you figure out the sweet spot to get the best reception.
What’s the best height to get the best reception?
It is as simple as this. The higher the antenna, the better the reception. But you need to make sure you’ve reached that height or otherwise making changes to it would be impossible which might cause more trouble than good.
Why use aluminum foil on the antenna?
The reason to wrap the antenna with foil is to grow the surface area. Besides that, it also improves the conductivity which is vital to enhance the signal.
How to get rid of static on FM radio?
If it is caused by the antenna, then remove it and try out to see if there is any static. If it is still there then it might be some other issue. And if it is caused by the antenna, then move around the antenna wire to see if the static fades away. Trial and error is the way to get rid of it.
