What to Look for When Buying Coax for HF Ham Radio


As you narrow down your list, this section talks about some of the most important considerations. Whether it is a coax for 144 MHz or any other frequency, these factors will help you make a decision you won’t regret.


When you are checking a coax comparison chart, one of the most important technical specifications is impedance. Expressed as ohms, it dictates the compatibility or functionality of the cable. If it is 75 ohms, it is best for video signaling. On the other hand, if it is 50 ohms, then it is better for wireless communications, including ham radio.


Differentiating ham radio coax cable types requires looking at their connectors. It can be male (PL-529) or female (SO-239). The right choice will depend on what is suitable for the radio or antenna that you are using. Both male and female connectors should have threaded connections to ensure a tight fit.


From the jackets to the inner conductors, the choice of material directly impacts the overall quality of the cable. Especially for outdoor applications, the components must withstand UV exposure, rain, and other external elements that can speed up wear. Plus, it should be built in such a way that it is easy to shape or bend without affecting its functionality.

Wire Attenuation

The more a cable attenuates, the more signal loss there is. Attenuation is lesser when a cable has a larger diameter. In turn, it increases the quality of communication by eliminating interferences.

Cable Length

One of the most important coax cable specifications’ ham radio, the right length depends on your needs. Most of the products in this review ranged from 50 to 100 feet. If it is too short, you won’t have the freedom to optimally position the radio and antenna so that you can have the best reception.


Do not forget to read reviews about the product and learn from the real-life experiences of other users. To avoid regrets, we recommend buying only from trusted e-commerce sites, where you can see genuine reviews. That said, Amazon, Walmart, and Home Depot are some of the best places to buy ham radio coax.

What is the Difference Between RG* and RG*X


You will find several types of coaxial wires. A common way to differentiate them is based on their gauge or thickness, which is expressed as RG or radio guide. The higher the number, the larger the central conductor is. If it is RG8 (RG*), it means that the conductor is an 8-gauge (or whatever the gauge is). There is also a version known as RG*X (such as RG 8x), which means it is thinner but the signal quality remains the same.

Is LMR 400 the Same as RG8

LMR 400 is one of the most common cable types. However, take note that it is not the same as RG8. Instead, it is common as a replacement to the latter. Nonetheless, keep in mind that LMR 400 has an aluminum wire as its center conductor. This makes it more difficult to bend, so it is best only for straight installations. More so, according to the ham radio coax cable loss chart, LMR has a lower loss.

Can RG6 Be Used for Ham Radio

Yes, RG6 coax is compatible even for ham radios. Nonetheless, while you can technically do so, we recommend using other types since RG6 can result in high losses. The latter will affect the reception quality and overall radio performance.


With the best coax for HF ham radio, it is easier to communicate over airwaves. These cables connect to an antenna or any other component while minimizing loss and interference. As a result, you can expect clearer communication at both ends. The overall quality and performance, however, depend on the specific product that you will use.
