AM reception can be very difficult because of the inherent succeptibility AM has to electrical noise and other sources of interference. The built-in antenna in most receivers – a coil and a ferrite ...

I am trying to help someone out, he has a Denon home theater receiver and gets pretty crappy AM radio reception with it using the included AM antenna. I tried a cheap amplified Radio-Shack AM/FM ...

This simple little circuit 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. It is further more designed to be used on ...

While we can’t argue that FM has superior audio quality and digital streaming allows even higher quality in addition to worldwide access, there’s still something magic about hearing a weak and fading ...

Yes, it's easier to cram a functional FM antenna into that little roof bump intended mainly for cell and XM reception. AM antenna is harder to do in limited space if you want decent reception. But it ...

Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor to ...

Greg Manfroi of WIUM/WIUW, Western Illinois University, Macomb, IL, sent us this idea on a construction method for the shielded-loop AM antenna. Start with the electrical specifications as described ...

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 ...
