Introducing the RFD-MDL406 — a truly unique HF Multiband Resonant Delta Loop Antenna designed to deliver exceptional performance from 40m to 6m bands. The antenna is resonant on 20m, 15m,10m and 6m while 40m, 30m, 17m, and 12m bands can be easily tuned using an external antenna tuner.

Thanks to its full-wavelength delta loop design, the RFD-MDL406 offers naturally low noise reception and a low take-off angle, ideal for long-distance DX communication. Its lightweight and compact structure makes it perfect for base stations or portable setups—no need to worry about space limitations or HOA restrictions.

Engineered with high-quality materials for durability and high wind-load resistance, this antenna ensures reliable performance in all weather conditions. With its excellent gain, low noise characteristics, and bi-directional radiation pattern, the RFD-MDL406 stands out as a powerful yet practical HF DX antenna that lets you hear the weakest stations and be heard across the world.

Salutes to you Debu for bringing out an easy to assemble 3 el loop fed yagi . Last week I assembled it and put it at a height of 5 m above the terrace . SWR through out is below 1.5 and 1.1 up to 200 khz from 28 MHz. Excellent quality of manufacturing . Today I fired it and made two contacts in the morning . Band was not open yet but received signals were 579 at my end and my reports were 599.I will give a detailed feedback back after few days . Once again Salutes to you dear Debu

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!
