i have a sony '70's table radio that just happens to posess the best a.m. performance i've ever seen on any radio. being the "typical guy" naturally i want to optimize even that. does anyone have a good home-brew external antenna and how do you configure the lead into the radio's existing loop system...if at all? i cannot see spending 60-80 dollars on a "select-a-tenna". thanks! frank

Here's a site I found awhile back:

The article mentions that you can omit the sense winding if the radio is placed near the loop. Hope that helps.

In my experience, a good internal AM loop antenna should be accepted as is. They are directional, so you can rotate the set for optimum reception.

Since loops are part of a tuned circuit, it would be tricky to modify them without messing up the tuning.
