MLBA-Mark 3
MLBA-Mark 4

The RF Systems MLBA-MK3 offers exceptional performance from 0.1 - 40 MHz.

The RF Systems MLBA-MK4 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-MK4 does start to fall-off sharply at about 32 MHz.
