In the world of portable radio setups, creativity often leads to practical solutions. One of my recent projects involved constructing portable antennas using travel clotheslines as support structures. This unique approach not only made the building process more manageable but also offered significant advantages in tuning and performance.
Design and Construction
For this project, I used two travel clotheslines and approximately 10 meters of silicone-coated AWG 22 wire to create a dipole antenna. The travel clotheslines provided a lightweight and adjustable framework, ideal for easy setup and transportation.
The key advantage of using clotheslines is the ease with which the antenna can be tuned. The design allows for simple adjustments in the length of the radiator, making it straightforward to achieve the desired resonance for different frequency bands. Any excess radiator wire is neatly stored within the clothesline structure, eliminating clutter and ensuring a clean setup.
Tuning and Performance
One of the standout features of this setup is the ability to tune across a wide range of frequencies, from 40 meters to 6 meters. By incorporating markers along the radiator during the tuning process, I was able to precisely adjust the antenna for optimal performance on each band. This method ensures that the antenna remains efficient and effective across multiple frequencies.
Conclusion
This innovative approach to building portable antennas demonstrates the versatility of everyday items in enhancing radio setups. The use of travel clotheslines not only simplifies the construction process but also provides a practical solution for tuning and adjusting antennas in the field.

Exploring End Fed Antennas with the Same Technique
Building on the success of my travel clothesline dipole, there’s exciting potential for applying the same technique to create End Fed antennas. Just like with the dipole, using travel clotheslines as support structures offers a unique and practical approach for constructing these versatile antennas.
End Fed antennas are known for their simplicity and effectiveness, especially in portable setups. By leveraging the adjustable nature of the clotheslines, you can easily configure and tune End Fed antennas to cover various frequency bands. This method allows you to manage the length and configuration of the radiator with ease, making it possible to tailor the antenna for optimal performance in different conditions.
Whether you’re seeking a compact and efficient solution for field operations or exploring new designs for your portable station, the same principles applied to the dipole can be used to craft effective End Fed antennas. Embrace the versatility of this technique and enhance your portable radio experiences with creative and functional antenna designs.
Stay tuned for future updates and experiments as I continue to explore the possibilities of portable antennas. Your feedback and ideas are always welcome!
