Can anyone tell me about them?? Are they any better or worse than wire
antenna?? Thanks for any comments about this Steve

That's a big topic. It depends on many factors like what kind of active
antenna you are looking at and comparing it to what kind of passive
antenna. A big factor is where you live. If you live in town with a lot
of local noise on a small lot an active antenna could be a good choice.
If you are far apart from your neighbors and have a good size lot a
passive wire antenna is probably a better choice.

You are going to have to give us more information.
