Crutchfield Customer Review (What's this?)

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

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

Written By ChicC, Charlottesville, VA on Monday, July 08, 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.
