WILSON 301133 Spring-Mount, High-Gain Cellular Antenna

The 301133 antenna from Wilson is a dual band antenna designed for use with any Wilson Dual Band amplifier. Its main benefit over other antennas we carry is it's shorter height and integrated spring. This makes it perfect for use with trucks and RV's, as the spring reduces impact damage to the antenna. The 301133 comes with a standard CB 3/8 x 24 threaded mount and the coaxial cable threads through the bottom of the threaded mount. If you need to attach the antenna to a horizontal bar, then we suggest the 901104 3-Way mount. (Buy.com)
