I'm not a fan of active indoor antennas for SW, as there are so many noise sources for them to pick up these days.
not to mention that usually this type of antenna gets connected to a receiver with sub-par front end circuit that gets over loaded by the amplifier and ends up only picking up the local AM sports radio regardless of where you tune.
obviously others may have had better experiences with them.
i am a fan of this antenna for SW listening, as it's pretty low noise and has a very small footprint: http://www.hard-core-dx.com/nordicdx/antenna/special/bromstik.html
