This circuit shows an active antenna that can be used for AM, FM, and shortwave (SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. This circuit is designed ...

If your hobby is chasing radiosondes across vast stretches of open country, and if you get good enough at it, you’ll eventually end up with a collection of the telemetry packages that once went up on ...

Has anybody here used these? Are they really much better than my cheap passive one? The one that I am looking at is here: I'm using one now. They help quite a bit. You can get cheaper ones, though.

GPS is a nifty piece of technology. GPS hardware needs to have a clear view of the sky because it's satellite based, so using your handheld unit can be a problem when the roof of your car is blocking ...

Although the concept of using local surface plasmon resonance based nanoantenna for photodetection well below the semiconductor band edge has been demonstrated previously, the nature of local surface ...

Short-wave listeners often are not able to, or allowed to, install a long-wire antenna or other large dimension antenna in or around the home. In such cases, the present active antenna, intended for ...
