*** A well-built broadband loop ( BBL ) usually also features low noise
as well. Obviously if you have an antenna tuning control on your
receiver, that can be used but probably to little effect.
We used a 6 foot wire BBL at last year's LBI DXpedition in NJ and other
than needing a preamp, which will be available this year, it was very
worthwhile. I believe we pretty much aimed it for peak toward Europe
and it worked equally well for MW and LW.
