The shape of an antenna can make a big difference in its performance. Researchers at the Johns Hopkins Applied Physics Laboratory have used shape memory alloy to construct an antenna …read more Continue reading Might Morphin’ Antenna
If you want to analyze an antenna, you can use simulation software or you can build an antenna and make measurements. [All Electroncs Channel] does both and show you how …read more Continue reading Antenna Measurement in Theory and Practice
[My Ham Radio Journey] wanted to see if a “common person” (in his words) could build an effective vertical ham radio antenna. If you look at the video below, the …read more Continue reading $40 Ham Antenna Works Six Bands
Ideally, if you are going to transmit, you want a properly-tuned resonant antenna. But, sometimes, it isn’t practical. [Ham Radio Rookie] knew about random wire antennas but didn’t want a …read more Continue reading Random Wire Antenna Uses No Wire
As far as hobbies go, ham radio tends to be on the more expensive side. A dual-band mobile radio can easily run $600, and a high-end HF base station with …read more Continue reading Few Things Are Cheaper than This Antenna
Here’s the thing about radio signals. There is wild and interesting stuff just getting beamed around all over the place. Phrased another way, there are beautiful signals everywhere for those …read more Continue reading Supercon 2023: Receiving Microwave Signals from Deep-Space Probes
Watch out, Gen X-ers — there’s a nostalgia overload heading your way, courtesy of this over-the-air TV simulator. And it has us feeling a little Saturday morning cartoon-ish, or maybe …read more Continue reading Broadcast TV Simulator Keeps the Nostalgia Flowing
The Hackaday comments section is generally a lively place. At its best, it’s an endless wellspring of the combined engineering wisdom of millions of readers which serves to advance the …read more Continue reading Is That Antenna Allowed? The Real Deal on the FCCs OTARD Rule
There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely …read more Continue reading A Simple But Effective Receiving Loop Antenna
There’s an old saying in the amateur radio community that when it comes to antennas all you need is a piece of wet string. This may be a little fanciful, …read more Continue reading You’ve Got The Portable Radio, Now What About The Antenna?
