This antenna is shorter than the standard Lynx antenna but will work fine for normal track stadiums. Flexible top. Always try and keep antennas away from metal for best reception/range. (don't tie them to a popup tent frame and keep away from speaker/PA magnets). NOTE: THIS ANTENNA CAN UNSCREW FROM ITS BASE, PLEASE ENSURE IT IS SCREWED ON TIGHTLY. Best to use it only on your receiver so a starter doesn't touch it.
