Description
RFD-CW5HF – Compact 5-Band Cobweb Antenna
The RFD-CW5HF from RF-DXing is a compact and efficient 5-band Cobweb antenna covering 20m, 17m, 15m, 12m, and 10m bands. Engineered for performance in limited spaces, this antenna measures just 6 feet x 6 feet and weighs only 4.5 kg, making it ideal for terrace installations and portable setups.
Constructed using durable fiberglass tubes, the RFD-CW5HF is designed to withstand the elements and offers long service life. The radiator uses 1.5 sq.mm high-quality, PVC-insulated pure copper wire.
This antenna has been extensively modeled using advanced simulation software, with accurate dielectric constants applied during the optimization process. It has been field-tested with successful QSOs, confirming its reliability and performance.
Key advantages:
-
Near-omnidirectional radiation pattern in the horizontal plane — no rotor required
-
Low noise reception, especially compared to dipoles and verticals
-
Wind-resistant up to 100 km/h
If you're seeking a space-saving, robust, and multi-band HF antenna, the RFD-CW5HF is the perfect choice for both seasoned operators and those with limited installation options.

Customer Reviews
I purchased Cobweb 5 band antenna in January 2025.I would say it is working really good at my QTH..The antenna is very nicely weight balanced, easy to mount. SWR is tuned to 1.1~1.18 in most of the bands.Deb is very helpful. Though he gave a nice documented instructions but still while assembling he was constantly helping over the call.
I mounted it on a 6m pole, at a height of 30m building rooftop.
Very low noise at all the bands. I would definitely recommend this antenna to fellow HAM's who live in urban area who does not have much space to mount yagi or dipole.
Thank you for your positive feedback on our RFD-CW5HF 5 Band HF Cobweb Antenna. We are thrilled to hear that it is working well for you at your QTH and that you found it easy to mount and well-balanced. We appreciate your recommendation to fellow HAMs living in urban areas with limited space for larger antennas. Thank you for choosing our product and happy Dxing!

RFD-CW5HF, 5 Band HF Cobweb Antenna
I purchased a RFD-CW5HF Cob Web antenna last August from RF-DXING and mounted it on a 30 ft (9m) guyed mast in my antenna farm along with 9 other HF/VHF antennas. It has become one of my primary DX antennas along with several other HF verticals and wire antennas. It arrived from India in perfect condition, was very easy to assemble and I had it up and operating in very little time. I am impressed by its construction and was slightly worried how it might behave in the harsh environment of the Canadian far north. After being exposed to gail force winds and temperatures ranging from <30 deg C in the summer and >-30 deg during the winter, it suffered absolutely no failures and continues to function as well as the day it was first installed. Right from day one I have been amazed by its ability to pull in some of the weakest signals, especially when I compare it with other antennas I am currently running. It is as good transmitting as it is at receiving. I highly recommend it to anyone looking for a horizontal alternative in an omnidirectional antenna.
PS The orange flagging tape you see in the picture I left in error when assembling the antenna outdoors. The idea was to warn anyone not to accidently walk into it before I put it up. I forgot it was there until it was to late.......
Thank you for taking the time to leave such a detailed and positive review of our RFD-CW5HF Cobweb Antenna. We are thrilled to hear that it has become one of your primary DX antennas and that it has withstood harsh weather conditions without any failures. We take great pride in the quality and durability of our products and are happy to hear that it has exceeded your expectations. We appreciate your recommendation and hope you continue to enjoy using our antenna. Thank you for choosing RF-DXING.
