Abstract
Abstract A rotary antenna connector includes a rotary shell rotatably fitted with a stationary shell. A plurality of radial grooves in the stationary shell are engaged by balls resiliently urged between the rotary and stationary shells. Engagement of the balls in the grooves holds an angular position of the antenna connector until the holding force is overcome by sufficient external manual torque.
