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 ...

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 ...

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 ...

PORTLAND, Ore. — A four-year skunk works effort at the University of Rhode Island in Kingston has cut the size of an antenna by as much as one-third for any frequency from the KHz to the GHz range.

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 ...

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 ...
