20 Meter Band HF Mobile Stick Antenna
The May Vary 20 Meter Band HF Mobile Stick Antenna is a fiberglass-mast solution designed for portable 20m operation. It uses a 4 ft stainless steel tunable whip atop a 4 ft black fiberglass mast and includes a standard 3/8-24 base mounting thread. Rated for up to 250 watts, this antenna suits mobile or temporary field setups where quick deployment is essential and space is limited.
GRA-CFS20 20 Meter HF Carbon Fiber Mobile Antenna
The GRA-CFS20 is designed for the 20 meter HF band with a 14.2 MHz center frequency suitable for mobile and portable use. It features an ultra-light carbon fiber construction at about 131 g, including the loading coil. The 3/8-24 connector is compatible with most HF mobile mounts used in the United States, delivering a balance of lightweight portability and performance.
Shark Antennas S-F20 Mono Band HF 20 Meter Mobile Vertical
The Shark HamSticks S-F20 is a single-band 20 meter mobile vertical with a 44-inch fiberglass mast and an integral coil. An adjustable, removable 48-inch stainless steel whip provides tuning flexibility. It carries a 250W max rating and uses a 3/8 x 24 thread base, which fits a wide range of mobile mounts commonly used in the U.S.
Shark Antennas S-FM20 Mono Band HF 20 Meter Mini Mobile Vertical
The Shark HamSticks S-FM20 is a compact 20 meter vertical designed for tight spaces. It uses a 24-inch mast and a 3/8 x 24 thread base, enabling versatile mounting options. Like its larger sibling, it is rated for up to 250W max, offering a convenient, space-saving option for mobile and field deployments.
Sumsoctober Stainless Steel Moxon Antenna Production Kit
This DIY kit by Sumsoctober includes a CNC-machined base plate and mounting frame tailored for shortwave Moxon construction using 20mm support rods. It’s designed for 20mm PVC or insulated metal rods, enabling flexible builds for 6m, 10m, 12m, or 15m bands. Stainless steel components offer weather resistance for outdoor or field use, with a solid platform for a true Moxon-style antenna.
Diamond Antenna M685S Monoband 6m Mobile Antenna
Note: While primarily a 6m solution, this Diamond Antenna M685S demonstrates how single-band mobile designs differ in dimensions and impedance. Its inclusion here provides a reference point when evaluating 20m moxon-oriented options, especially for operators considering band-specific efficiency and mounting constraints. It operates with a 52-inch height and a 200W rating, offering a baseline for comparison against 20m-focused designs.
Buying Guide: Key Considerations for 20 Meter Moxon and Related Mobile Antennas
- Band focus and versatility: If your goal is a true 20 meter moxon in compact form, prioritize kits or antennas explicitly designed for 14.0–14.35 MHz operation, or those marketed as 20 meter handheld/mobile solutions with adaptable mounting.
- Mechanical mounting: Check thread sizes (commonly 3/8-24) and mounting hardware compatibility with your vehicle or mounting rack. Consider stainless steel hardware for corrosion resistance in outdoor use.
- Weight and materials: Carbon fiber and fiberglass are lightweight and durable, improving portability. Heavier stainless or aluminum builds may offer durability but affect transportability.
- Power handling: Most mobile options are rated around 200–250W. Confirm your transmitter’s output and ensure the antenna can safely handle those power levels without overheating or anodic degradation.
- Length and height: Mobile and field-ready options vary from compact 24–44 inch masts to larger configurations. Measure mounting space and allowed envelope on your vehicle or field structure.
- Durability and weather resistance: Stainless steel components and weather-resistant finishes extend life in outdoor environments, especially for field days or permanent installations.
- DIY vs. ready-made: DIY kits offer customization for specific bands and rods (e.g., 20mm rods), while ready-made units emphasize ease of use and quick deployment. Assess your technical comfort level and long-term maintenance goals.
- Performance expectations: A moxon-style design typically emphasizes directional gain and bandwidth. Compare center frequency alignment, potential gain, and SWR behavior across typical operating bands to meet your operating goals.
- Field and mobility use: For mobile operation, evaluate mounting options, vibration resistance, and the ability to tune or replace parts on the road or at the site.
When selecting a 20 meter solution, consider whether you prioritizse portability, a fixed installation, or a modular approach that can adapt to multiple bands in the future. Matching mounting hardware, frequency coverage, and power handling with your radio gear will help you optimize range, reliability, and ease of use.
