Getting The Best Coax for Ham Radio Buyers’ Guide

The best coaxial cable purchase comes with a satisfying feeling. No doubt, you are set to use it for a long time. But the essential duties to carry out before buying one matters most. What are the critical factors to consider? See for yourself here.

01. Cable Types

When opting for a coax, it is essential to state your needs, especially when it comes to the standards.

Existing are two main classes of coax. The first consists of 75 ohms and applies mostly to video signaling. In comparison, the other one has an impedance of 50 ohms, primarily used for data and wireless transmission.

Both are great and contribute to coaxial technology. The ones with 75 ohms are our very own RG59U and RG6U. In terms of availability, you’ll find this class of coax in 1000, 500, and 100-foot reels.

Examples for the latter, which is 50 ohms, are RG174/U, RG188/U, and RG316/U. If you want to get the best from 50 ohms cables, apply them in a situation whereby an operator builds coaxial wires in a field.

Wait! Do they have foot-reels, too? Of course, they are, and the same: 1000, 500, and 100 foot-reels make up the 50 ohms coax.

In all, what’s with their 26 AWG center conductors? Nothing much. It increases flexibility and makes the cables fit for high-powered applications.

The best fit for losing less signal is 50 ohms cables with 100, 200, and 400-foot reels. They are highly efficient for wireless implementation. Talk of shielding — each comes with a Teflon outer jacket.

02. Level of Frequency

Skin effect: it is a condition, whereby energy changes positions initially from the central core to the outer jacket as the rate rises.

It is, without a doubt, another factor to consider before making a purchase.

First, why are you buying this cable? Does it require a high or low level of frequency? Technical operators use this method to understand how well energy can travel at a given rate. Simply put, the distance gets shortened as the frequency increases.

03. Wire Attenuation

When a cable attenuates, it yields a large amount of signal loss. You can simply tell what you want by considering if the selected coax does the same.

If your cable continues to attenuate, more signal loss for you. Practically, say, we have two wires with a tendency of attenuating.

The one with a larger diameter will likely be in form than the other. In other words, attenuation occurs less in a cable with a larger diameter.

Now, let’s check between these two coaxes: an RG59/U with 14AWG center conductor and an RG/11U with 20 AWG center core. Sure, to say, the former carries a signal double the length of the latter.

04. Characteristics Impedance

The characteristic impedance of a cable is critical for making any purchase. It can tell how well the cable you’re opting for will perform.

To state clearly, this factor is a joint measurement to check the capacitance per unit length with the inductance per unit length.

If all you want is optimal performance, know one thing: the characteristic impedance must go hand in hand with the inductance/resistance of your moving capacity.

Types of Connectors

Users find one thing challenging, and that’s to solder multiple coaxial cables together — seems impossible, right? You can actually do that, but you need the connectors because that’s their job.

Most companies use the soldering method. And often, when a breakdown occurs, these connectors are the first things that go into a replacement.

Here are the main types of connectors — about three or four of them:

  • SMA: works for most RF applications.
  • Reverse Polarity SMA: this works mostly for wireless connections
  • U FL: is the smallest type of connectors and is often compatible where other ones wouldn’t fit because it is tiny.
  • BNC: this is a little bigger than the others, and its application area is based on amateur radios and test equipment.

Quick Note: RG cables vary in types and functions. Checking for specifications is necessary before making any purchase. If you want, use excellent technical aid.

FAQ’s of Best Coax for Ham Radio

What are the components of coaxial wires?

You must have heard the word “coax” if not coaxial cable — both have similar meanings, as they work for Radiofrequency and applications.

It consists of vital parts, as follows.

The surface that looks sharp and tiny and appears like a mouth is the central core, otherwise known as the primary conductor.

Covering the connector is a dielectric material. In some cables, you’d see foam dielectrics. They contribute to transmission and better retention.

Lastly, the whole cable is shielded with an outer jacket that prevents signal loss. The primary purpose of this outer coat is to shell the current passing through without letting in impurities or moisture that could be kinky if in place.

What makes one coax better than the other?

Every proper working coax out there has probably achieved the hype because of its shielding type. Obviously, shielding matters and its method vary in different coaxial cables, with one to four layers.

The best coax for ham radio involves a shield with better coverage or percentage cover. Well, you may want to consider trying the one with a tight metal braid.

Conductivity works well, plus it has about 95% coverage. Hold on. Where goes the remaining 5%? Nowhere, I guess.

Manufacturers place an extra layer (two metallic foil), which helps resist some of the Electromagnetic Interference attempting to pass through tiny holes in the braid.

What does RG mean?

Dating back to the world war II era brought about the existence of Radio Guide (RG). The military back then used RG efficiently for survival, as it depends on communication and radio frequencies.

RG is a set standard that helped them to distinguish these cables’ grades and functions. Although the name has evolved, the world still uses this same old method of naming. Interestingly, there was no reason as to how the names came into place. They all came randomly.

What are coaxial cables used for?

Coaxial cables are tightly on point when it comes to powering applications and sending transmissions.

They can carry high-frequency signals without disruption from Electromagnetic Interference (EMI). EMI is a form of interference that disturbs the smooth flow of electrons.

These cables are standard in our day-to-day applications if you begin to observe them. They work perfectly fine for radio communication. One of the active sets of users is ham operators.

These people make use of coaxial cables regularly. The same thing applies to the telecommunication industry, and there are many active users there. You’ll also find these things in homes, schools, and offices.

What’s best for microwave line transmission?

There are tons of micro-coax available in the coax world. In fact, these are the most common types.

In a situation whereby a low level of frequency leads to a low RG power, considering the phase matching, RF shielding, and operating frequency tends to make a micro-coax preferable.

What tip does the author have for me concerning the best coax for ham radio?

Here, it is essential to keep to two rules:

  • First, your field runs are a primary factor. It would be best if you kept it as short as possible.
  • Secondly, opt for a cable with low loss power compatible to your operating frequency.

Now, let’s do simple physics. Every cable experiences loss; the tendency is what matters. The conductors carry electrons through the wire, and they slow down as they meet with resistance.

Remember, resistance is part of the phase, and electrons can’t flow through without encountering a form of resistivity.

Still, you can slow them down by using a more substantial and thicker cable.

Notably, the path in which Radiofrequency travels depends partially on the wire — not wholly. As the radio wave increases, RF gets closer to the wire.

Sure, to say, a cable with thicker conductors has enough space for retention. Thereby decreasing the level at which signals escape. Indeed, broad and well-shielded conductors are much better than slimmed ones.

Another thing; consider the length of the cable. Next is the operating frequency. After that, research the chart of losses exhibited by popular cables and see their losses. Are they acceptable to you?

What does the N connection mean?

It merely describes the exhibition of low loss VHF and UHF but standard UHF and high-powered radio equipment.


Are you still in doubt scouting for the best coax for ham radio? Check the charts of the popular ones available and see if their loss is acceptable to you.

Also, consider the guide in this piece to put you through the process. If you still need some help, opt for technical support.
