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 ...

SIMPLE, EASY-TO-USE FM/AM RADIO WITH HIGH QUALITY SOUND: Portable handheld radio with digital tuner has a simple, easy-to-use interface, with antennas that pick up both AM and FM signals EASY-TO-SEE ...

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 ...

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 ...
