Performs as described. No surprises Install was quick & easy. You have to admire the artful look of the antennae itself.

Pros: Great look. Multiple set up options.none


Decent antenna for the size

Mike S from Minneapolis, MN on 2/8/2014

Crutchfield Customer Review (What's this?)

This is a decent antenna - useful if you need something small for the bedroom. I have a Terk HDTVa in my living room that works much better. The issue with this antenna is that the signal drops consistently when I walk around my bedroom, but I don't want something huge sitting on my dresser. If you have more room, go with the Terk HDTVa.

Pros: Small size, easy to set up.

Cons: Signal disrupted easily by movement in room.

Crutchfield Customer Review (What's this?)

Pretty good quality for the price. I looked at other places but Crutchfield had more choices and suprisingly better prices.

Pros: Works great looks good easy to set up and use

Cons: coax cord a little short but usable

Works fairly well

ChicC from Charlottesville, VA on 7/8/2013

This antenna works ok. Keeping in mind that it's an inside unit and not very big don't expect it to do to much. I had to mount it fairly high up for it to work properly. You get what you pay for in this situation.
