The Comet CHA-250HD is a high-quality vertical multiband antenna for amateur radio operators who want to combine maximum performance with a compact and practical installation. This renewed version of the popular CHA-250B offers excellent performance on multiple HF and VHF bands without the need for radials, an antenna tuner, or complex adjustments.
Thanks to its wide frequency range of 3.5 to 57 MHz for transmitting and 2 to 90 MHz for receiving, this Comet antenna is a versatile solution for amateur radio operators and shortwave listeners looking for one antenna for various applications. Whether you are active on the 80-meter band, the 40-meter band, the 20-meter band, or the 6-meter band, the CHA-250HD is ready for immediate use.
Broadband performance without radials
What distinguishes this vertical multiband antenna from many other HF antennas is its ease of use. No radials are needed, and an external tuner is also superfluous in most cases. Thanks to its clever transformer design, the SWR typically remains below 1.6:1 over almost the entire transmit range.
This makes the antenna particularly suitable for locations where available space is limited or where strict regulations apply to antenna installations. With the Comet CHA-250HD, you get a versatile antenna without having to set up an extensive antenna field.
Improved design for long-term use
The CHA-250HD features a redesigned construction where the upper aluminum element has been replaced by a flexible whip. This allows the antenna to better withstand wind loads and significantly reduces the load on the lower sections.
In addition, the renewed transformer housing has integrated cooling fins that dissipate heat better during operation. This contributes to stable operation and a longer lifespan for the antenna.
With a length of over 7 meters and a weight of only 3.2 kilograms, the antenna remains relatively easy to install and maintain.
