How to make an antenna for receiving (only) broadcast AM
"Beverage antennas are highly directional."
Living in Portugal in the 1950`s, I used a Beverage antenna to listen to
the CBS Evening News from WCBS in New York, and WWL in New Orleans.
Whenever one station faded, I just rocked the dial and the other station
would be there. Portugal is on Greenwich time so the Evening News was
around midnight local time. By then, most of the Europeans had signed
off.
All you must have for a Beverage antenna is a long wire, say 2
wavelengths long, aimed at the targeted broadcaster.
For 690 KHz that would be 2,850 feet of wire, just over 1/2 a mile of wire.
