What customers say
Customers overwhelmingly praise the Chameleon Antenna Spike Base for its exceptional stability and robust quality, making it essential for portable amateur radio. Users consistently highlight the durable, high-grade materials that ensure longevity outdoors. The primary benefit is the dramatic improvement in vertical antenna setup reliability, easily outperforming lighter mounts. Operators in POTA and SOTA confirm the spike penetrates various ground types effectively, securing masts firmly even in wind. While noted as a premium purchase, the consensus is that the investment is justified by the significant enhancement in deployment speed and rock solid foundation it provides for serious HF operations. Minor weight concerns for ultralight trips do not detract from its core value as critical infrastructure.
Know before you buy
The spike base is designed for use with the CHA Hybrid HF, MPAS, MINI, and MICRO antenna systems.
No, this is a drill-free, ground-mounted system. You simply push the 15-inch stainless steel spike into the ground by hand or with a mallet.
The base includes a dedicated counterpoise thumb screw, allowing you to easily secure your ground wire without needing additional tools.
While the stainless steel is durable and rugged, the product is not rated as weather-resistant. It is intended for temporary portable deployment rather than permanent outdoor installation.
The spike base features a standard 3/8"-24 thread, which is compatible with most standard amateur radio antenna whips and the specified Chameleon systems.
