We have the Automatic, and it works well. We also had the Sensar IV installed, so that I would have a rising arm to install our 14" non flexible WiFi Antenna and Ubiquity too for horizontal traveling. Had the shop A/B switch the install of the Automatic and the Sensar IV, so if we ever find we're just on the fringe go what he Automatic an pull in, I have the Sensar IV available. It does have the ability to pull in stations from a bit further distance...
If I did not want to have a raisable mast, I would have just run with the Automatic. Slick install, and good easy to understand lights to help you tune channels.
Best,
Smitty
