The DXP-406 Standard Cobweb Antenna is a versatile multiband antenna designed for amateur radio operators seeking excellent performance, a compact footprint, and convenient operation from a fixed station. Covering the 40, 30, 20, 17, 15, 12, 10, and 6-meter bands, it is an excellent choice for home stations, rooftop installations, and other permanent antenna setups.
Proudly manufactured by a small family-owned business, the DXP-406 reflects a hands-on approach to product development, with attention to detail and a genuine understanding of the needs of amateur radio operators. Each antenna is designed with a focus on practical functionality, durability, and the enjoyment of amateur radio.
