Indoor, I'd go with the RCA ANT1550. It's perfect. It blends in with a white wall (though also comes in black), and is flush. I know, indoor antennas are hideous things I'd never want in my living room, even rabbit ears are ugly. I can't vouch for the quality of reception on this yet, however, since I have not gotten one but plan to in the future. I currently use rabbit ears, but fortunately for me, the signals are so strong where I live I have rabbit ears completely collapsed and I get everything perfect.
There's a flat type just like that that rates higher (borderline excellent/superior) than my cheap RCA 'wings' (which pick up everything but is rated as 'good') and requires zero aiming but the only thing which keeps me from paying for it is the obvious resemblence to a 'smart antenna' which i have heard suck.
