The importance of a shortwave antenna.

, ,

Much comparison has been made of the various models available today, but relatively little attention has been paid to available antennas. After all, no matter how good the receiver is, without a good antenna, nothing will be heard. In simple terms, the longer the piece of wire you can connect to any receiver, the more you will hear,

On the MW (AM) band, the antenna function is provided by a coil wound on a ferrite rod inside the receiver casing. On the FM band, a telescopic whip is provided. For SW (shortwave) an external antenna will provide the best results.

The simplest external antenna is a simple piece of wire connected to the “external antenna” socket of a receiver.

There are various models available from a simple wire with a plug on a plastic bobbin, to a retractable length of wire several metres long. Whilst these might be very portable and easy to carry, but no attention has been paid to matching the antenna to the receiver.

The importance of a shortwave antenna.

The best shortwave antenna will always be a resonant wire outside the building housing the receiver. Such antennas are normally fed using coaxial cable which provides shielding from interference generated inside and gets the active antenna element away from such noise sources.

A matched end fed longwire antenna is one of the simplest external antennas available, and will provide a huge performance improvement over an untuned piece of wire.

This is normally achieved using a long piece of wire (10M or so) and an “unun”, in simple terms a matching device to ensure maximum signal is provided to the receiver, all enclosed in a weatherproof housing suitable for outdoor mounting.

An even better solution than this is the “tuned” antenna, such as a dipole, normally reserved for amateur radio operators. The antenna is tuned by adjusting the length of the wire elements to the desired frequency.

The antenna elements are matched to the coaxial cable feeder using a balun. For transmitting applications this is vitally important, if the antenna is matched to the transmitter all the energy will be transferred to the antenna, and conversely when receiving, all available signal will be fed to the receiver. In this version the wire elements have frequency markings and can be unwound from the bobbin for the correct length.

shortwave antennas

For those of us that wish to receive shortwave signals but don’t have the room for an external antenna, an active loop may be the solution. Normally 60cm-100cm in diameter, an amplified loop antenna is a wideband device that can be mounted near a window, or outside. The MLA-30+ antenna is one of these and many users have reported great results using these both indoors and outdoors as their circumstances permit. Powered by a standard USB source, this amplifier comprises a power injector and amplifier separated by a length of coaxial cable.

Coaxial cable antenna

Another fixed location antenna that can be used for shortwave, VHF and UHF is the discone. This antenna has a very wide bandwidth from 25-1300 Mhz and is hence very convenient to use on a wide range of radio bands.

In summary there is a wide range of economical antennas that can make a huge difference to shortwave reception.

Amateur Radio: A Lifeline in Death Valley National Park

, , ,

 

In the vast expanse of Death Valley National Park, a remote desert in southern California, modern connectivity often falls short. On a fateful Saturday, April 6, a family’s adventure took an unexpected turn when their vehicle became trapped in mud in a hazardous area, leaving them without cell service. In this critical moment, amateur radio proved to be their saving grace.

Caleb Gustwiller, KD8TGB, a dedicated radio amateur from Ohio, sprang into action upon receiving the distress call. Monitoring the 10-meter band, Gustwiller managed to pick up the call sign and approximate location of the ham in distress. Despite losing the signal amidst the noise, he swiftly turned to the Parks on the Air® Facebook group, rallying fellow hams to lend their ears and assistance.

Thanks to the collective efforts of the amateur radio community, several hams reached out to emergency officials in southern California. This timely intervention led to the rapid rescue of the stranded family by park rangers, averting what could have been a tragic outcome. The Black Swamp Amateur Radio Club emphasized the gravity of the situation, stating, “Without Caleb hearing this distress call, it could have quickly become a very deadly situation for the operator and his family.”

This remarkable incident underscores the invaluable role of amateur radio in providing communication lifelines, especially in remote and challenging environments. It serves as a powerful reminder of the importance of community, collaboration, and the enduring spirit of ham radio operators worldwide.

Rediscovering the Power of Shortwave Radio: A Journey into Untapped Potential

, ,

As a passionate enthusiast of all things radio-related, stumbling upon a thought-provoking article titled “Why Is Shortwave Only ‘the Radio of Last Resort’? Its powerful new capabilities remain largely unexplored” by Simon Keens of Radio World ignited a spark of curiosity within me. Shortwave radio, often dubbed as the ‘radio of last resort,’ has long lingered in the shadows of modern communication technologies. Yet, its potential remains vast and largely untapped.

In an age dominated by digital streaming services and satellite communication, shortwave radio might seem antiquated to some. However, delving deeper into Keens’ article revealed a different narrative – one that speaks of resilience, versatility, and the potential for innovation within the realm of shortwave broadcasting.

The article shed light on the multifaceted capabilities of shortwave radio, highlighting its ability to traverse vast distances with minimal infrastructure. Unlike its counterparts, shortwave signals can propagate over thousands of kilometres, making it an invaluable tool for global communication, especially in remote or disaster-stricken regions where traditional means of communication may falter.

What struck me the most was the notion that shortwave radio is often perceived as a ‘last resort’ rather than a primary means of communication. This begs the question: why is such a powerful medium relegated to the sidelines? Is it due to the allure of modern technology or simply a lack of awareness about its potential?

Keens’ article challenged me to reconsider my own perceptions of shortwave radio and prompted me to embark on a journey of exploration into its capabilities. As I delved deeper into the world of shortwave broadcasting, I was astonished by the wealth of content and diversity of voices that permeate the airwaves.

From international news broadcasts and cultural programs to amateur radio operators and clandestine stations, shortwave radio offers a tapestry of voices that transcend borders and ideologies. It serves as a platform for free expression and cultural exchange, fostering connections between individuals and communities across the globe.

 The resilience of shortwave radio in the face of adversity cannot be overstated. During times of crisis, when other forms of communication may fail, shortwave radio often emerges as a lifeline, providing vital information and fostering a sense of solidarity among listeners.

Yet, despite its undeniable strengths, shortwave radio continues to face challenges in an increasingly digitalised world. The proliferation of internet-based communication platforms and the decline of traditional broadcasting have posed significant obstacles to the growth of shortwave radio.

However, rather than viewing these challenges as insurmountable barriers, we should see them as opportunities for innovation and adaptation. As technology evolves, so too should our approach to shortwave broadcasting. By embracing digital advancements and exploring new modes of content delivery, we can breathe new life into this time-honoured medium.

My encounter with Simon Keens’ enlightening article on shortwave radio served as a catalyst for reevaluation and exploration. It reminded me of the enduring power and potential of this oft-overlooked medium and inspired me to advocate for its revitalisation.

As we navigate an increasingly interconnected yet fragmented world, the role of shortwave radio as a beacon of communication and cultural exchange has never been more vital. It is my hope that through continued innovation and collaboration, we can unlock the full potential of shortwave radio and usher in a new era of global connectivity and understanding.

A Note From Garry On The Upcoming Eclipse

, ,

As we eagerly anticipate the upcoming solar eclipse on April 9, it’s essential to understand how this celestial event can influence HF signal propagation. A solar eclipse occurs when the moon passes between the Earth and the Sun, momentarily blocking the sun’s rays. This interruption in solar radiation can have significant effects on the Earth’s ionosphere, particularly in the altitude range of 60 to 90kms.

During a solar eclipse, the reduction in solar radiation leads to a corresponding decrease in ionization in the ionosphere. This reduction in ionization can disrupt HF signal propagation, affecting radio signals, GSP navigation systems, and shortwave communications. The sudden change in ionospheric conditions can create challenges for radio operators and listeners alike.

However, despite the potential disruptions, the solar eclipse also presents a unique opportunity for amateur radio operators and shortwave listeners. It offers a firsthand opportunity to observe and study the effects of a solar eclipse on radio wave propagation. In particular, shortwave listeners may notice improved reception of LW signals, including time signals, as discussed in our recent blog post.

We encourage listeners to share any signal reports logged during this period, as it will contribute to our collective understanding of solar eclipse effects on radio communication.

This blog post is brought to you by Garry from Tecsun Radios Australia.

With years of experience as a dedicated hobbyist, Garry is passionate about exploring the fascinating world of radio communication and sharing his insights with fellow enthusiasts.

Stay tuned for more updates and insights from Tecsun Radios Australia. Happy listening!

Best regards,
