I want to try to make a homemade ferrite antenna to improve the AM reception on
an old radio. I can't find any place on the internet that gives a simple
explanation of the how to's. All I want to know is how many winds of copper
wire and what lead connects to what radio connection. And also, just the most
basic of antenna principals involved.

Anyone have any suggestions?

thanks
