The VLBA stations are located in areas with limited radio interference, and widely spread across the country. The distance between any two stations is known as their baseline. The longer the baseline, the better the angular resolution. The most widely separated antennas are at Mauna Kea in Hawaii and St. Croix in the U.S. Virgin Islands, which are 8,611 km apart. While each VLBA antenna is identical, each location is unique. Each station also has a webcam, so you can view them in real time (http://www.vlba.nrao.edu/sites/SITECAM/NLcam.shtml)
