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 wire antenna ...

Most ham radio operators will build an antenna of some sort when they first start listening or transmitting, whether it’s a simple dipole, a beam antenna like a Yagi, or even just a random wire ...

First responders could boost their radio communications quickly at a disaster site by setting out just four extra transmitters in a random arrangement to significantly increase the signal power at the ...

The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in ...

The circuit is intended to produce a simple antenna that has the capability to be tuned at medium wave frequency which complements the antenna of a radio receiver, without having to use any external ...

Mike Murrey hired on as engineer at WJMC(AM/FM) and WAQE(AM/FM) in Rice Lake, Wis., back in 1998. He took one look at the 459-foot tower serving WJMC on 1240 kHz and knew it would need to be replaced ...
