The cobweb antenna is an array of dipoles fed from a common feedline. Don’t get sucker punched by the gain figure of “Up to 5 dBi gain will allow you to work DX easily — even on QRP.” There is a trade off for wrapping a dipole back on itself to reduce its size.
What is the difference between a Cobwebb and a dipole?
So as you can see above, the Cobwebb has more signal strength over a large majority of the antenna pattern when compared to a dipole. The Cobwebb is a closed loop design and it’s also a quieter antenna. This often results in hearing signals much clearer too.
Does cobweb use low budget accessories?
We don’t use low-budget accessories. This Cobweb Antenna is using a double 1:4 balun that can handle a little more then 2 KWatt, also the wire’s can handle the load of high powered stations.The design is the same as the low power Cobweb Antenna only using other materials to handle the load.
Where did you get the inspiration for your cobweb aerial?
Much of the inspiration (not to mention technical details) was obtained from G3TXQ’s CobWeb webpage although there are many sites that also detail the aerial’s features and construction. The antenna complimented my “low-band” horizontal dipole nicely and gave me the most useful HF bands (20-10m) without needing an ATU.
