Joe,
An important point is that the transponder needs to see the track not only
straight down but also forward and back by at least a few inches. As you cross
the line the transponder makes a number of hits: weaker as you approach/depart,
strongest as you pass directly over. It triangulates on the signal strength
coming and going to find the exact millisecond you are centered over the loop.
Ideally there should be an uninterrupted cone of vision from the transponder
bottom to the asphalt. AMB tells you the maximum height is 2 feet. But they do
not tell you there is a also practical minimum height of around 9-12 inches:
too
small a cone of signal means too few hits to accurately position you. That
means
don't do the obvious and mount it on the frame. This generates a weak-signal
warning to the T&S system and you will likely get a love note at pit in to
change it. (Been there, done that.) Mid-height inside the wheel well is AMB's
suggestion, but outside the front valance works great too and provides easier
access for removal.
Hope this helps,
Gary Schneider

Subject: [Fot] AMB RECHARGEABLE TRANSPONDER Questions
I am about to install.
What is the favored location on a TR3-6 chassis for location of the
transponder?
Any caveats?
Orientation?
Thanks!
Joe
