A properly tuned FM transmit antenna is essential for your broadcast system to work properly, yet fewer than 25 percent of engineers tune their FM antennas, based upon my 40 years of observation. Not ...

The humble radio antenna has become more of a design feature in recent years, but sometimes the shape is dictated by function, as well as form.

When broadcasting was in its infancy, amplitude modulation (AM) was the principal modulation system being researched and developed. Once efficient generation of useful RF signals was discovered and ...

Car Radio Antenna Frequency: FM 88MHz-108MHz, AM 535KHz-1605KHz; Gain:3dBi; Extend Cord: 16 feet; Connector:DIN male Application: fits most vehicle truck car marine boat stereo receivers media head ...

I recently had a chance to try out a really cool-looking — at least in the opinion of some — antenna for my truck. The brand itself doesn’t matter much as these are all similar in design: flexible ...

[Eric Brasseur] built a radio-detecting snake that consists of a LED that lights up when around reasonably strong radio waves. Near an FM radio mast you’ll find a huge amount of waste energy being ...

Together with a good directional antenna this high performance two-stage antenna amplifier for the VHF FM broadcast band will enable you to capture far removed (DX) stations. Alternatively, it will ...

Apple has issued its first public response to growing pressure by the FCC and other groups to activate FM terrestrial radio features inside iPhones for end-users. In a statement, the company said it ...
