WebMar 31, 2024 · Electronics This article presents the methodology to design a single-fed circularly-polarized antenna with low front-to-back ratio (FBR). A circular-patch (CPatch) antenna has been incorporated within the rectangular-cavity, made of, substrate integrated waveguide (SIW). WebThis antenna is complete with exception of the 5 feet of ¾ inch Class 200 PVC pipe needed for the antenna. Individual shipping of the 5 ft antenna is $14 so we rather you go to …
The DBJ-1: A VHF-UHF Dual-Band J-Pole - Ed
WebThe antenna is allowing those other signals to reach the receiver at a higher voltage. Which has the potential to cause receiver front end to overload. By using an antenna with a higher Q, you're filtering those other signals at the antenna. Incidentally, that's the same reason I don't think the Edison Fong is a good antenna for GMRS. WebThe completed antenna can be seen mounted to the author’s roof in Figure 5. If you do not have the equipment to construct or tune this antenna at both VHF and UHF, the completed antenna is avail- able from the author, tuned to your desired frequency. The cost is $20. E-mail him for details. Ed Fong was first licensed in 1968 as WN6IQN. .net 6 object to byte array
