Choosing the Right Wire for Your Antenna

Choosing the Right Wire for Your Antenna



Wire is a crucial component in the world of ham radio operators. It is not only necessary for making radios work, but it also plays a vital role in radiating signals. With so many different types of wire available, you may wonder which one is the best choice for your antenna. In this blog, we will explore the various considerations to keep in mind when selecting wire for your antenna, and how to make the most of your budget without sacrificing performance.

The Importance of Wire

Your antenna is responsible for radiating your signal and sending it around the world. Therefore, it is essential to choose the best wire for the job. While there are many different types of wire, the most important factor to consider is whether it can conduct electricity effectively. As long as the wire can conduct electricity, it will likely meet your requirements.

The Best Wire for Your Antenna

When it comes to the best wire for your antenna, there is no one-size-fits-all answer. However, there are some key characteristics to look for. Firstly, ensure that the wire is strong enough to withstand various weather conditions, including wind, rain, and even lightning strikes. While it is unlikely that any wire will stand up to a direct lightning strike, opting for a durable wire can reduce the risk of damage during a storm.

The Quest for the Perfect Wire

As a young ham radio operator, I was always on the lookout for a wire that would give my signal an extra boost. However, as I gained more knowledge and experience in the field, I realized that the material and thickness of the wire were not as critical as I initially thought. What mattered most was the source of the wire and its ability to withstand environmental factors.

Finding the Right Wire

In my search for the perfect wire, I explored various options, including hard drawn copper wire. While hard drawn copper wire is incredibly strong, it is quite challenging to work with due to its springiness. For permanent antenna installations, hard drawn copper wire may be suitable, but for practicality and ease of use, I found that multi-stranded PVC-covered wire was the best choice. Speaker wire, in particular, proved to be a cost-effective option as it provides twice the length for the same price.

Joining Wires Together

One common challenge encountered when working with wire is running out of it due to trial and error during antenna experiments. However, there is a simple solution to this problem – joining wires together. If you find yourself with two lengths of wire that are slightly shorter than what you need, you can twist them together to create a longer wire. While this may seem like a temporary fix, it can save you money and provide the length you require for your antenna. You can also use a knot or heat shrink sleeve to secure the join for a more permanent solution.

Strength and Weight Considerations

When selecting wire for your antenna, it is essential to consider both its strength and weight. A wire that is too heavy may sag, affecting the performance of your antenna. However, the thickness of the wire is not a significant factor in terms of its conductive properties. As long as the wire is thick enough to avoid breaking, it will be suitable for your needs. Additionally, there are specialized wires, such as Kevlar-covered wire, that offer exceptional durability and longevity.

Cost-Effective Wire Options

Contrary to popular belief, you don't have to spend a significant amount of money on wire for your antenna. In fact, you may find usable wire in unexpected places, such as coils of wire with the covering removed. Speaker wire, which is readily available and affordable, is an excellent choice for many ham radio operators. It is multi-stranded, PVC-covered, and typically more cost-effective than other options. Remember, the specific metal content of the wire is not as crucial as its ability to conduct electricity effectively.


Choosing the right wire for your antenna is essential for optimal performance. While there are various types of wire available, focusing on strength, durability, and cost-effectiveness will help you make an informed decision. Remember to consider your specific needs, and don't be afraid to experiment with joining wires together to achieve the desired length. By selecting the appropriate wire, you can ensure that your antenna efficiently radiates your signal and provides you with an enjoyable ham radio experience.
