Things to Consider before Buying Coax for HF Ham Radio

Getting your hands on the best coax cable for HF ham radio, you believe the coax to be your partner for a long haul. But for that, there are some duties for you to fulfill. Learn about the most important factors for you to consider.

Types of Cables

Before you buy anything, you need to know about your requirements, especially if you want a standard cable; you have to know the types.

There are two types of coax between them; the first one is 75 ohms, better for video signaling. The second one has 50 ohms of impedance which is used for wireless and data transmission.

Both are great at what they do. The RG6U and RG59U are 75 ohms, and they have reels of 100, 500, and 1000-foot long.

RG316/U, RG188/U, and RG174/U are the 50 ohms cable. For best performance, use them where an operator creates coaxial wires.

Do not worry about foot-reels because all of them have it, with variations of 1000, 500, and 100-foot reels, so that carrying the cable around will be a piece of cake.

Moreover, the center conductors 26 AEG increase their flexibility and make them usable for high-powered usage.

The 50 ohms with the 100, 200, and 400-foot reels are the best option if you do not want to lose many signals. They are best for wireless usage. Each cable has shielding of Teflon outer jacket.

Frequency Levels

When energy changes its position from the central base towards its outer jacket, the rate increases is called the skin effect. You should, without a doubt, consider this factor before you buy a cable.

Understand the reason you are buying the cable for. Think if you need a low or high frequency level. The technical operators understand energy to travel by using this method. Simply put, radiofrequency will increase as the distance shortens.

Cable Size

This is another crucial factor you should count on. You have to consider a lower-sized cable to make sure your camping, hiking, or other related works become easier, especially when you are carrying an antenna. For these purposes, you need a lightweight unit.

But with some devices, the size will reveal its power. And so, for powerful tasks, you will need a powerful unit on your rooftop or car. You will use larger and heavier units for that.

Cable Material

If you want to use your cables for longer, then choose high-quality cables. HF applications are poor quality coax, and they are demanding, so they will not last long.

The construction quality is a big deal when you are going to buy a coax. Plus, connectors made with flaunt materials will be a bad call to buy. In case, they can break off soon.

For less budget, you can go for either aluminum or tinned copper. But the best option is always copper.


Well, versatility might not be major stuff if your primary concern is to use coax cable only for HF Ham Radios. But, if you are working with multiple radio stations, various devices, two-way radio type stuff, and other applications, well, then you must look for a coax cable that offers versatility without any signal loss.

Wire Attenuation

If the wire you're using attenuates loss a tremendous amount of signal, you have the wrong wire for sure. You can judge the quality and find out what you want.

But, if the cable leaves no chance to attenuate, then it's sure of more signal loss. In that case, a cable having a large diameter can be your choice. This type of cable assures fewer signal leakage issues.

Characteristics Impedance

A must-watch fact to notice before you leave for the shop - the characteristics impedance will tell you it's going to perform. To give you a clear idea, the impedance factor works to inspect the inductance and capacitance length per/unit.

If your top-to-bottom preference is the best performance, then you should think of impedance as a major concern to perform equally in both cases of inductance and capacitance. In this way, you can ensure maximum signal flow without any type of leakage.

Male & Female Connectors

Basically, a coaxial cable offers both male PL-259 and female SO-239 plugs. The plugs are truly essential to connect your electronic device to the coax cable. And the major fall comes to hand because of poorly-built plugs.

As long as I have studied, I found that the connectors are vastly soldered for better safety and protection for prolonged usage.

But, I'm not saying that non-molded connectors are not worthy; they do fine as well - a good piece indeed. Sometimes, you would love to do a bit of heat shrink tubing to ensure the connectors don't fall for moisture.

Besides, the male and female connectors must come with an applicable length to fit the devices correctly, like receiver, transmitter, radio, antenna, tuner, etc. Otherwise, the cable won't get a secured grip on the other connectors and eventually breaks the signal flow.

Coax Frequently Asked Questions

1. What are the most trusted coax for ham radio brands?

Normally Workman, Bingfu, Cablesonline, RFAdapter, MPD Digital, BOOBRIE, Ancable, YOTENKO, Extreme Consumer Products etc. are the brands on which most of the customers rely. These are the famous brands known for building and selling coax for ham radios globally.

2. What is the difference between RG8 and RG8X?

Well, RG 8 is a 50 Ohm cable at 12 AWG, which is thicker than the RG 8X. The RG 8X is a thinner and mini version that contains 16 AWG center conductors. Whereas the RG 8 one is usually used in amateur radios.

In terms of quality, both of them are the same. They are mainly distinguished from each other on the basis of overall gauge and AWG.

3. Is LMR 400 the same as RG8?

LMR 400 is the latest version that is supposed to replace RG8. There are also durability issues that are to be considered, such as LMR400 can be broken shortly, whereas RG8 plays a flexible role. So, they are not the same.

4. Can RG6 be used for ham radio?

The RG6 is to be used under 150 MHz only. So, it is entirely usable for radio transceivers. But, as the losses are relatively high, you can invest your pennies into a 50 Ohm cable.5.What's best coax for microwave line transmission?

There are vast choices available out there in the market. In this case, you should choose something, considering the operating frequency, phase matching, and RF shielding.

Final Verdict for Coax Buyers

If you require muscular signal strength and top-notch transmission, the best coax for HF ham radio is an absolute necessity for you.

Following the above guidelines and looking at your preferences, can lead you to a perfect choice within your budget. However, you can take time to check the desired length, build quality, and compatibility with devices.
