Hi All, I picked up a Little Tarheel II the other day, just the base and whip. Making a manual controller for it is simple. What I am wondering is what type of sensor it uses to detect rotation. Tarheel told me it counts the revolution of a magnet, so a Hall effect or reed switch seems likely. Anybody know for sure what it is? Another question: On the Tarheel site is says not to use the antenna on a trailer hitch type mount. I want to mount the antenna on the tongue of my trailer, which would put it between the car and the tear drop trailer. It looks to me that as long as I have it on a stub mast that brings it up above the roof of the car and the trailer that it should work fine. How far above the ground plane is ideal? I am not going to use it in motion so I can have it at whatever height is optimal. Thanks!
