Antenna balls are both fun and functional. Place one on your car’s antenna and you not only have something to make you smile but also make it easier to spot your vehicle in parking lots. You can select from designs such as the traditional yellow happy face or the more creative collectibles from Disney's line. Sports fans can pick one wearing their favorite team’s helmet while others can show off their careers. You can even find personalized antenna balls for a good price with promo codes. When shopping for antenna balls, remember to check Giving Assistant for coupons.
