I guess it depends on what you consider indoors ;-) I have one mounted in my attic with a directional motor on the base. Terk -38 I think is the model but I forget the motor brand.
Before you spend money on just any antenna, go out to www.antennaweb.org They have a program that will tell you what signals you can receive and in what direction the antenna should point all from your home address.
The other thing you should watch in the site output is the stations are then color coded so you need to get an antenna with that color coding or higher to receive it. A good way to be sure what you buy will get the stations you expect.
