Antennas are a key component to any RF gadget. But antennas often only perform well over a narrow band of frequencies. For some applications, this is acceptable, but often you …read more Continue reading Electromagnetic Mechanism Makes Reconfigurable Antenna
Software-defined radio is all the rage these days, and for good reason. It eliminates or drastically reduces the amount of otherwise pricey equipment needed to transmit or even just receive, …read more Continue reading Antenna Mount Designed For On-The-Go SDR
It stands to reason, that should you wish to communicate with a satellite, whatever antenna you use should point at that satellite. Some of us have done this by hand, …read more Continue reading AntRunner Is The Satellite Antenna Mount You Need To Take With You
The Raspberry Pi Compute Module 4 has a built-in WiFi antenna, but that doesn’t mean it will work well for you – the physical properties of the carrier board impact …read more Continue reading Design Your CM4 Carrier With WiFi Performance In Mind
Electromagnetic interference problems can be a real headache to debug. If you need to prove what causes your WiFi to slow down or your digital TV signal to drop, then …read more Continue reading Measuring Electromagnetic Fields With Just an Arduino and a Piece of Wire
If there’s one thing that amateur radio operators are good at, it’s turning just about anything into an antenna. And hams have a long history of portable operations, too, where …read more Continue reading Wind-Up Tape Measure Transformed into Portable Ham Antenna
It may come as a shock to some, but TV used to be a big deal — a very big deal. Sitting down in front of the glowing tube for …read more Continue reading Retrotechtacular: Measuring TV Audiences with the “Poll-O-Meter”
Modern ham radio operators often face restrictions on antennas. This has made small antennas more popular, despite some limitations. [Tech Minds] reviews the GA-450 indoor active HF loop antenna and …read more Continue reading Affordable HF Loop Antenna Reviewed
[G3OJV] knows the pain of trying to operate a ham radio transmitter on a small lot. His recent video shows how to put up a workable basic HF antenna in …read more Continue reading Ham Antenna Fits Almost Anywhere
The lower the frequency of radio transmission, the more antenna that will be needed in general. [OM0ET] wanted to work the 80M to 20M ham bands and decided to turn …read more Continue reading Frame Antenna Works the Low Bands
