Did Radio Shack discontinue that loop antenna? It was very good, but its
selectivity was poor at the upper end of the band. OTOH, the
Select-A-Tenna is very selective; great if you have an interference
problem. I wouldn't want to be without one. (Both of them must be manually
tuned, hence the reference to selectivity.)

This active antenna is excellent: http://www.ccrane.com/am-antenna.asp .
It also requires manual tuning. So, none of these are as simple as the
plain wire idea, but they're not hard to use, either.
