What is a CobWebb antenna and what is its gain? It is a very efficient horizontally polarised omni-directional antenna for the 14, 18, 21, 24 and 28 MHz bands, with a gain of 7 dB over an isotropic radiator (7dBi).
The CobWebb is a full size half wave dipole on each of the 5 amateur bands, 14, 18, 21, 24 and 28 MHz. The CobWebb is 5 separate full size dipole antennas, each bent into a square. This makes it very small (only about 8 foot square) Time Owned: more than 12 months.
This eight-band (40, 30, 20, 17, 15, 12, 10, 6 Meters) full half-wave and 1500 Watt Cobweb Antenna is perfect for restricted space or portable operation. Sky-gray fiberglass spreaders and nearly invisible wire elements blend in with your surroundings while standing tough against nasty weather.
Sep 12, 2021 · The cobwebb antenna originally designed by Steve Webb (G3TPW) is a fairly simple antenna to build, requiring only a few hand tools & simple skills.
Sep 22, 2023 · If you want an HF antenna that covers the 20, 17, 15, 12, and 10-meter bands, you quickly end up with an antenna like a Cobweb. I ran into the 7-band AWK Cobweb and after a year in operation it was time for a personal review.
A great document that can guide you in making your own cobweb aerial. The cobweb antenna it is basically a 5 band antenna comprising of 5 full half wave dipoles for each band - between 10 meters and 20 meters, the antenna is also resonant on 6M and can be modeled even for VHF frequencies.
The EAntenna Cobweb antenna is a lightweight and quick to set up antenna for portable operation according to G3TPW. The Cobweb antenna operates on the five upper shortwave bands 20, 17, 15, 12 and 10m. The five folded dipoles are fed via a common balun, only one feed line is required.
Building a CobWebb Antenna - Homebrew a cobwebb antenna for the HF bands. This page describe a cobwebb multiband antenna resonating on 14 18 21 24 and 28 MHz. The cobweb antenna model can be considered a fan dipole, or better, multiple dipoles fed in parallel.
This clip illustrates my progress from start to finish building a homebrew single wire Cobweb antenna for the five amateur bands; 20m, 17m, 15m 12m and 10m.
Apr 9, 2017 · Project - Cobwebb (or cobweb) antenna. A DIY GUIDE - BUILD YOUR OWN COMPACT MULTIBAND HF ANTENNA. Living in a densely populated area antennas are an issue here. Officially I can place one antenna provided it is situated at the back of my house and not higher than 5 meters above the point where the antenna or mast meets the roof line.
