This antenna weights 2.1 ounces and is what I use in the backcountry when out of cell phone range. I've made contacts well over 150 miles and through satellites using it. I don't know the fellow who made the video but he did a fine job!
So, if you have your amateur radio license, build this antenna. It can save your tail, and also doubles as a tarp pole.
Nice little antenna project. Going to have to try it out. It is a good feeling when you see someone using your design and having fun with it. 73 n0oxk Jeff
Jim... Yeah, I've laminated them into plastic sheet, used copper tape on plastic sheet, etc. The carbon arrow shaft idea is final design of several attempts and gives me double duty, plus I can stack elements off the end for more gain if I want.
Dryer I understand that part. The question is whether you have tried to etch an miniature antenna on ceramic substrate with a much higher Q than air. I mostly designed microwave antennas and of course the wavelength was much shorter as I recall about 10.5" in the 2.4 GHz ISM band. I routinely made antennas that made postage stamps look big, some had a forward gain or 5-6 db. like the size or smaller than the patches in GPS units. Jim

Jim, I've made antennas etched on printed circuit board...log periodics, mostly...for use in the 1.2 ghz band and for cell phone boosting. In fact, I have a dual band one setting here on the desk for cell phone about 4" square. My dad etched much smaller antenna patches for satellite telemetry back in his day.
phat, Dryer, This is true. Samuel Finley Breeze Morse is buried in my families burial plot in Illinois, my mothers grand mother was a Morse. They always called her grandama Morse surprisingly enough. When I was a kid I was very proficient at it. Jim

No kiddin'? That's cool, Jim! I'm an avid code operator. It's still the most reliable mode of radio communication and the first "digital" mode. It was a sad day when the FCC stopped requiring Morse code for ham licenses. Not only was it a right of passage, it was/is invaluable training. The decision of the FCC to eliminate code was yet more dumbing down of license process. Morse is fundamental to radio and signaling.
