The Comet CWD-230 is a professional-grade, broadband HF dipole antenna designed using the T2FD (Tilted Terminated Folded Dipole) principle. It is an exceptional "all-rounder" for operators who want a single, high-performance antenna that covers a massive frequency range without the constant need for an antenna tuner.
Key Performance Highlights:
What sets the CWD-230 apart is its wideband capability. While traditional dipoles are cut for a specific band, this folded dipole design allows for seamless operation across the HF spectrum.
- Transmit Frequency Range: 1.8 MHz - 30 MHz
- Power Handling: Rated for 150W (PEP), making it perfect for standard 100W transceivers.
- Low SWR: Typically maintains an SWR of less than 3.0:1 across the entire HF range, reducing wear and tear on your radio's finals. 2.0 or less (2‐18MHz), 3.0 or less (18‐30MHz)
- Quiet Reception: Because it is a closed-loop design, the CWD-230 is inherently quieter than standard wire dipoles, significantly reducing man-made static and atmospheric noise.
Physical Specifications:
Despite its broad frequency coverage, the CWD-230 is surprisingly manageable in terms of size and weight.
- Total Length: 25 Meters (approx. 82 feet)
- Weight: 3.1 kg
- Input Connector: SO-239 (M-Type)
- Configuration: Folded Dipole with matching Balun and Termination Resistor
Installation Versatility:
One of the best things about the CWD-230 is that it isn't picky about how you hang it. Whether you are limited by trees, poles, or roof space, this antenna adapts:
- Horizontal Dipole: Best for general NVIS (Near Vertical Incidence Skywave) and regional communications.
- Inverted-V: A great space-saver that provides a good balance between local and DX performance.
- Sloper (Tilted): By tilting one end down, you can enhance the T2FD's natural ability to provide a low angle of radiation for long-distance contacts.
Who is this for?
The Comet CWD-230 is the "set and forget" solution for:
- Emergency Services: Users who need to jump between frequencies instantly without retuning.
- Amateur Operators: Those with limited space who cannot install separate antennas for every band.
- SWLs (Shortwave Listeners): Its massive receive range (up to 150 MHz) makes it a powerhouse for wideband scanning.
Tech Tip: For the best results, ensure the antenna is mounted at least 2–3 meters away from metal structures and at a height of at least 6 meters above the ground.
