I am a long time follower of this thread. I was hot to trot to buy a rotor, but my heals cooled. Now my heals are hot again, and I am in the market. for an antenna turn-nee-thing again. However the single coaxial signal and power/control feed is less important to me now, well not important at all. What I noticed from last time I was in the market a few years ago is the price of this rotor went way way up.... it was a steal for about $40, cheapest on the market, and now it lists for $99. It is now in wide field of other brands in this price range. I am likely to go with an Antenna-Craft or Radio-Shack for $55. As this thread shows (early posts) using the single feed for both signal and power/control is a compromise, i.e., signal attenuation. Of course it can be used as a conventional rotor. With that said, at it’s current $99 list, it is no longer the interesting steal and bargain it once was to me, single-feed or not. The antenna I'm turning is small; the el-cheap-o-rotors are just as good I am sure as the Aspen 100. My only question is did the quality improve with the price?, because if you read early post you will see the weak link in these units.
