Description 

RF-DXing Antenna RFD-CW7HF – 7-Band HF Cobweb Antenna


The RF-DXing Antenna RFD-CW7HF is a 7-band HF Cobweb antenna covering 40m, 30m, 20m, 17m, 15m, 12m, and 10m. Technically, it also supports an 8th band, as the 6m band can be easily tuned using an inbuilt tuner.


The antenna is constructed using high-quality fiberglass tubes, ensuring excellent durability and long service life. It has been carefully designed and optimized using advanced antenna simulation software, with accurate dielectric constants applied during the modeling process for precise performance optimization.


The RFD-CW7HF is engineered to withstand wind speeds of up to 110 km/h and exhibits significantly lower noise pickup compared to conventional dipole and vertical antennas. The radiator elements are made from high-quality 1.5 sq.mm PVC-insulated pure copper wire, ensuring reliable electrical performance and longevity.
This antenna has undergone extensive field testing and numerous QSOs, clearly demonstrating its efficiency and real-world performance. With its near-omnidirectional radiation pattern in the horizontal plane, it eliminates the need for an expensive antenna rotor.


If you are looking for a compact, long-lasting, and efficient multiband HF antenna for limited spaces, the RFD-CW7HF is an excellent choice for serious HF operation
