DXP-306 Field Cobweb Antenna

Portable Multiband Performance | 30 to 6 Meters

(Ships within 20 days of order placement)

The DXP-306 Field is a versatile, fully modular Cobweb antenna designed for amateur radio operators who value portability, flexibility, and reliable performance. Covering seven amateur radio bands—30, 20, 17, 15, 12, 10, and 6 meters—it is an excellent choice for POTA (Parks on the Air), Field Day, portable DXing, and other outdoor operating activities.

Proudly made in the USA by a small family-owned business, the DXP-306 Field is developed with a hands-on approach and a genuine understanding of the needs of amateur radio operators. We believe in practical engineering, durable construction, and products designed by people who share a passion for amateur radio.

Designed for Portable Operation

The DXP-306 Field features quick-release clamps that simplify assembly and disassembly, making it convenient to transport and deploy in the field. Its fully modular design allows you to configure the antenna for only the bands you intend to use. For example, if you operate exclusively on the 6, 10, 12, and 15-meter bands, you can install only those elements and store the remaining ones until needed.

Each band element connects to the distribution box through color-coded connectors, making band identification straightforward and helping prevent connection errors during assembly.

Durable Construction for Outdoor Use

Built with UV-resistant materials, including fiberglass, acrylic, stainless steel, and silicone-insulated tinned copper wire, the DXP-306 Field is designed for long-lasting outdoor use.

Our prototype has remained outdoors for several months, exposed to direct sunlight, rain, storms, and winds of up to 25 mph (40 km/h). Extensive field testing has also resulted in hundreds of QSOs with stations throughout the United States and many countries around the world.
