Just a few further observations on the Winegard Razor.
We finished our last trip through quite a bit of eastern and central Iowa (top to bottom).
The Razor only needs to be aimed in two directions to get full range coverage in a circle. Aiming in one direction was sufficient for us to get all networks found in multiple metro areas. More than one channel found carrying major networks in all our camping locations.
The antenna will easily find all transmitters within 45 degrees either direction off front and back of the antenna (hour-glass pattern). However; I found the antenna can add 2 bars in signal strength by pointing at the transmitter so it is very directional for getting far away signals, or those hidden in valleys. This works fine for me with 2 amplifiers allowing up to 20 decibel gain.
Radio Shack is gone for now so finding their amplifiers will be harder now. Someone most likely made them for R.S. So far I have found that the Razor seems to be doing a better job for us in campgrounds frequented by us. I did not bother to do scans after dark since days are long up here now.
So comparing extreme range of Razor to my Winegard III/Wingman will have to wait until fall or heavy cloud conditions for signal bounce. I am hoping for the similar 150 to 200 mile range under those conditions.
The antenna should be attached with 2 bolts (option 2) when using the longer boom. It could be too easy for wind or vibrations to loosen the single bolt and allow antenna to be ripped off the boom.
