MLBA-Mark 1
MLBA-Mark 2

The RF Systems MLBA-MK1 offers exceptional performance from 0.1 - 40 MHz.

The RF Systems MLBA-MK2 is a longer 66 foot (20 meters) version and offers even stronger performance ... especially on on longwave and medium wave. See the dashed line in the above chart. The MLBA-MK2 does start to fall-off sharply at about 32 MHz.
