Steve Everson is also looking for a transponder. Can you tell me what type we are looking for exactly? Must be AMB? Is the AMB TranX 160 (yellow housing) OK? Your advice would be appreciated.
"I asked the very question of AMB and got this response
Thank you for your e-mail. First, let me explain the specifications for the TranX160 (for karts) and the TranX260 (for cars) transponders:
TranX160-
Max Speed:160km/h (100mph)
Max Height:30cm/1ft
TranX260-
Max Speed:300km/h (180mph)
Max Height:60cm/2ft
You may find you have some success with the TranX160 transponder on your car, but we cannot guarantee that it will work on a car. The specifications are made not only based on speed of the vehicle, but also take into account other things such as possible detection height, electrical interference between vehicles, and the amount of metal on a car compared to a kart. I would recommend you purchase a TranX260 transponder for your car as that transponder was specifically designed to work with that vehicle."
As I read it the yellow one MIGHT work ok but not guaranteed - the red ones (and more expensive) are the designated units.
There is one for sale on race cars direct, posted today. Try copy and paste this link http://www.racecarsdirect.com/listing/40953/amb_tranx_260_dp_transponder.html
