The Rugged Ridge reflex antenna implements a shorter antenna design and a flexible material in its construction, making it a practical antenna solution for any Jeep TJ or JK (adapters included). lower antenna height significantly reduces the risk of the antenna being struck by tree limbs, trail hazards and even those damaging automated car washes. The reflex antenna is so resilient that it just bends over to release anything that may become hung on it and then returns to an upright position. Fitted with the proper threaded adapter for the application makes the reflex antenna a breeze to install. Available in multiple sizes- 6, 9, 13, 15 and 21-Inch lengths.
