In hopes of getting better reception (compared to the little grey wire that Yamaha supplied), I bought ordered the Terk Edge. It arrived in two days and I set it up right away. My favorite station over on Long Island, has always come in at my house, but was weak, had some static background and would cut out as I stood in certain spots around the living room. As a side note, this station usually comes in pretty well in the car. The Terk powered up and all I got was silence! I moved it around as far as the wires allowed and adjusted the gain knob, nothing! I called Cruthcfield for tech support to see if there was something else to try. After talking and re-checking the Terk, the Tech said to try a local station. Nothing! When I turned down the gain to almost zero, the local one came in. The Tech said he would send out another Terk, as this one seemed to have a problem, right from the factory. The second unit arrived and does now pull in the weak station, although not perfectly, it is much better than Yamaha's little grey wire antenna.
Pros: Pulls in the weaker stations better than the Yamaha factory wire antenna.
Cons: It took two units as the first one did nothing at all, and was much worse than the factory wire antenna.
