If you’re new to ham radio, it can be tricky to know where to begin. You’re faced with so many technical choices, from the type of radio to the antenna and power supply. One critical component that is often overlooked: the coax cable.
A coax cable is vital for ham radio because it carries signals to and from your antenna. Without the right cable, even the best transceiver in the world won’t perform as it should.
Whether you’re just getting started with ham radio or are more experienced, Moonraker offers a wide range of tips to help you find the best equipment.
In this blog, we explore what to look for in your first coax cable and why it matters. We’ll also highlight some starter-friendly options from Moonraker, your trusted name in radio communications for over 40 years.
Why Coax Cables Matter in Ham Radio
Coaxial cable (coax, for short) acts as the bridge between your radio and your antenna. Its job is to transmit RF (radio frequency) energy with minimal loss of signal. Although it can sound simple, not all coax cables are created equal. The wrong choice can lead to poor signal strength, interference, and even damage to your equipment over time.
If you’re a new operator, your main goals should be:
- Keeping signal loss to a minimum
- Ensuring compatibility with your setup
- Staying within budget while planning for future upgrades
That’s where a quality coax cable from a reputable supplier like Moonraker comes in.
What to Look For in a Coax Cable as a Beginner
Here are the most important factors to consider when buying your first coax cable for ham radio:
1. The Type of Cable
The most common types of coax cables for amateur applications are:
- RG-58. Flexible and affordable, this coax cable is ideal for short runs or setting up on-the-go. However, it suffers from higher signal loss at higher frequencies.
- RG-213. Thicker and more durable with lower loss than RG-58. A good all-rounder for fixed stations.
- LMR-400. A low-loss, high-performance option for longer cable runs or VHF/UHF frequencies. More rigid and usually more expensive, but worth the investment. We also have our own alternative to LMR-400 in the Formula-Zero cable.
2. Frequency and Power Handling
If you plan to operate mainly on HF bands (1.8–30 MHz), RG-213 could be ideal. But if you’re venturing into VHF or UHF territory (above 30 MHz), where losses increase, a low-loss cable like LMR-400 could be a better choice.
3. Length of Run
A ‘Length of Run’ is the total distance your coax cable travels from the radio transmitter to the antenna.
The longer that a coax cable is, the more loss it causes. For lengths under 10 metres, RG-58 might do. But for anything beyond that, or if you're aiming for long-term reliability, investing in a better cable like RG-213 or LMR-400 is wise.
4. Connector Compatibility
Make sure your coax cable ends are terminated with the right connectors for your equipment. Moonraker supplies a wide range of pre-terminated coax cables so you can plug and play with confidence.
5. The Quality of the Cables
Cheaper cables are easier on your wallet initially, but are likely to cost you in performance and durability later. That’s why it’s vital to look for quality shielding, solid connectors and reputable brands. Moonraker offers both in-house and branded coax solutions that pass the test.
Our Top Picks for Beginners
At Moonraker, we stock an extensive range of coax cable options for ham radio operators of all levels. Here are three top picks for those just getting started:

We offer budget-friendly, flexible coax cables that are perfect for learning the ropes. These are best used for short cable runs or portable setups. They come terminated with quality connectors and ready to use.
Moonraker RG-213/U Premium Coax
These are brilliant for fixed stations. Offers better power handling and reduced loss compared to RG-58. It’s a solid choice if you’re after a solution to use over the long-term, and you’ll notice the signal difference.
Moonraker Low-Loss Coax (LMR-400 Equivalent)
These cables are ideal if you’re planning to operate on VHF/UHF or want the best signal retention possible. Although they’re slightly pricier, your future self will thank you when you upgrade your station.
Don’t Forget Organising those Cables
One thing new ham operators often overlook is how messy and unmanageable cables can become, especially once you start expanding your set-up. That’s why Moonraker also offers a wide selection of cable organisers to make life easier.
Your cables will not only look neater, they will be less vulnerable to accidental disconnections, damage and signal interference.
