Chameleon B3D Broadband Base Dipole HF Antenna

The Chameleon Antenna B3D is a broadband base dipole built for real-world HF operation where space, visibility and installation options may be limited. It is available in three total wire lengths: 18.3 m [60 ft], 36.6 m [120 ft] and 44.5 m [146 ft]. The 18.3 m [60 ft] model covers 80 m to 6 m, while the 36.6 m [120 ft] and 44.5 m [146 ft] models extend coverage from 160 m to 6 m when used with an antenna tuner. The design supports multiple installation styles, including inverted-V, horizontal dipole, low-profile stealth layouts and portable field deployments.

Key Features

• Broadband HF coverage with a suitable antenna tuner
• Available in 18.3 m [60 ft], 36.6 m [120 ft] and 44.5 m [146 ft] versions
• Frequency coverage from 3.5–54 MHz or 1.8–54 MHz, depending on model
• Suitable for NVIS, regional and long-distance DX communication
• Flexible installation as an inverted-V, horizontal dipole or stealth wire antenna
• Low-visibility wire construction for restricted or urban locations
• Rugged 16-gauge tinned copper Kevlar PTFE wire rated from -70°C to 150°C [-94°F to 302°F]
• SO-239 UHF connector for standard coaxial feedline connection
• Lightweight and practical for portable, emergency and field operations

Typical Applications

• Home HF base station antenna for restricted or compact properties
• HOA, urban and low-visibility antenna installations
• Emergency communications and preparedness stations
• NVIS operation for local and regional HF communication
• Portable field operation, POTA, SOTA and temporary deployments
• Single-antenna HF setups for new or returning radio amateurs
• Broadband receive and transmit coverage where antenna simplicity matters

Specifications

Why Choose the Chameleon B3D?

• One antenna, many bands: The broadband design gives wide HF coverage without traps, coils or frequent hardware changes.
• Excellent for restricted sites: The low-profile wire layout is well suited to gardens, urban lots and locations where antennas need to remain discreet.
• Simple deployment: Install it as an inverted-V with a single centre support, as a horizontal dipole, or adapt it to your available space.
• Built for real use: Rugged wire, weather-resistant construction and a practical SO-239 feed connection make it suitable for long-term outdoor service and field operation.

• Two dipole wire legs in the selected length version

Performance Notes / Setup Guidance

The Chameleon B3D is intended to be used with a suitable antenna tuner. For best results, install the feed point as high and clear as practical, keep the wire away from metal gutters, fences, power lines and building wiring, and use quality coaxial feedline with appropriate strain relief. The antenna can be deployed as an inverted-V using a single centre support, or as a horizontal dipole when two end supports are available. Lower installations can improve NVIS performance on the lower HF bands, while higher and clearer installations generally improve DX performance. Always observe safe clearances from overhead power lines and follow local installation rules.

Choose the 18.3 m [60 ft] version when space is limited and 80 m to 6 m operation is required. Choose the 36.6 m [120 ft] or 44.5 m [146 ft] version when you have more room and want coverage down to 160 m. Add the Chameleon B3D Broadband Base Dipole to your station for a flexible, stealth-friendly and field-proven HF antenna system that is ready for everyday operating, emergency communications and portable radio work.
