When a busy schedule or poor weather makes riding indoors a reality, the Garmin Tacx USB ANT+ Antenna connects our ANT+ trainer to the computer, allowing us to take full advantage of enhanced training software. Interactive software makes riding indoors more meaningful and enjoyable since we can race friends or send data to our coach. The antenna is connected to the computer via a two-meter long cable. The receiver is positioned near the trainer, so the signal clearly transmitted is communicated to the computer and software of choice.
