Various systems for monitoring wheeled vehicles (such as shopping carts) are disclosed. The system can include an RF antenna unit that is buried and is configured for bi-directional communication with the electronics on the cart. In some embodiments, the antenna comprises a plurality of transmitters, which can emit synchronized signals. In some embodiments, the antenna comprises a radiating cable, which can emit a signal along some, substantially all, or all of its length.
