Chameleon Antenna CHA-BV-SO239 Antenna

The system is designed for rapid deployment and can be fully assembled by one person in under 10 minutes. The telescopic design and included spike mount allow you to get on the air quickly without needing complex tools.

While the telescopic whip allows for manual tuning across the 6.9-30 MHz range, using an antenna tuner is recommended to achieve the best SWR across all bands. It helps fine-tune the match, especially when operating near the edges of the frequency range.

The CHA-BV-SO239 is rated for 300W SSB and 200W CW/Digital. It is well-suited for most portable amateur radio setups, but you should avoid exceeding these power limits to prevent damage to the components.

Yes, the radial system is essential for efficient signal propagation and stable grounding. Because this is a vertical antenna, the radials act as the counterpoise, which is critical for achieving a low SWR and effective radiation pattern.

While it is weather-resistant and built with stainless steel and aluminum, it is primarily engineered as a portable field antenna. If you plan to leave it up permanently, you will need to ensure it is securely guyed and protected against high winds or harsh, long-term environmental exposure.

The spike mount is designed for soft ground, such as soil, sand, or grass. It is not suitable for concrete, rocky terrain, or hard surfaces, so you may need to consider an alternative mounting base if you plan to operate in those environments.
