Radioshack Stubby Race Scanner Antenna 1.7 Inches (43mm) High BNC Connector
I used this antenna with my Uniden Bearcat 75 XLT scanner at three race weekends last year (six total races plus many practice sessions). I used it at Daytona, Pocono and Atlanta and had 0 problems with reception. I could even pick up the radio signals while tailgating in the parking lot during practice. It was nice not having an antenna that was getting caught in the headphone cords or anything else throughout the day.
