Description
MA-50 Dipole: A versatile portable HF antenna for amateur radio enthusiasts who need to deploy an antenna from a single upright.
When it comes to portable HF antennas, reliability and versatility are paramount. The MA-50 antenna stands out as a robust solution designed specifically for amateur radio operators who demand performance and flexibility in their equipment. Whether you’re setting up your station on the go or optimizing your existing setup indoors or outdoors, this antenna delivers key features that cater to both functionality and ease of use.
Key Features and Benefits
Frequency Range and Tuning Flexibility: Operating within a frequency range of 14-50 MHz, the MA-50 covers essential shortwave bands used for communication, DXing, and emergency preparedness. Its telescopic design allows operators to adjust rod lengths precisely, accommodating various frequencies as outlined in the specifications. This adaptability ensures optimal performance across different bands, making it suitable for both standard operations and DIY modifications below 14 MHz using negative V configurations.
SWR Performance: With a specified SWR of <=1.5, this antenna delivers efficient energy transfer from your transmitter to the radiating elements. This level of performance ensures that power output is maximized while minimizing losses due to mismatched impedance, which translates into clearer signals and improved communication reliability.
Power Handling Capability: Rated at 200 watts CW (continuous wave) and FT8 modes with reduced power requirements, the MA-50 offers versatility for various operating modes. Whether you’re engaging in Morse code communications or utilizing modern digital modes like FT8, this antenna provides sufficient margin to handle your transmission needs without compromising on quality.
Compact Design: With a fully extended rod length of 5.6 meters and a total weight of just 1430 grams (including the storage bag), portability is a standout feature. Its lightweight yet durable construction ensures it can be easily transported to field day events, emergency setups, or remote locations without excessive burden.
Material Quality: Constructed using aluminum alloy and featuring anodization for added durability, this antenna combines strength with corrosion resistance. The Balun base interface (M14) is designed to withstand the rigors of outdoor use while maintaining reliable electrical connections. Its M female connector ensures compatibility with a range of transceivers commonly used by amateur operators.
Storage and Transportation: Included in the package is a storage bag measuring 57.5 x 11 x 7.5 cm, which neatly houses all components when not in use. This feature simplifies transportation and protects the antenna during transit or storage, making it an ideal choice for travel or temporary setups.
Operational Guidance
Rod Length Recommendations: To achieve optimal performance across different frequency bands, the MA-50 provides specific rod extension guidelines. For example, at 50 MHz, extending two sections plus 10 cm ensures resonance and minimal SWR; while for lower frequencies like 14 MHz, pulling out twelve sections plus 7 cm is recommended to maximize efficiency. These adjustments allow operators to fine-tune the antenna based on their specific requirements.
Installation Considerations: While the MA-50 is designed for ease of use, it’s important to follow best practices during installation. Using wind ropes to secure the antenna in place ensures stability against environmental factors such as strong winds or accidental movement. Proper grounding and electrical connections also contribute to optimal performance.
