Stainless Steel Whip Antenna

This whip antenna assembly displays not only our antenna and screw machine manufacturing capabilities but also our assembly or value-added portion of the business. The rod is formed from .100" 302 stainless steel through multiple different station setups on our CNC coilingbending equipment then are trimmed, deburred and ready for assembly. The antenna ball is composed of .250" 304 stainless steel which is formed on our screw machine with programmed memory to make setups quick, consistent and efficient.
The antenna ball is then swaged to the rod to complete the assembly. A rare feature that Sterling provides is our pull testing capabilities that will verify strength of the assembly to ensure the ball cannot be easily removed from the rod. This part is subject to a 100 pound pull test, which is tested on our custom built (in-house) pull testing equipment that is calibrated annually by a certified outside source.
The finished antenna assembly measures 11.32" in length and is good representative of the many antennas that our antenna department manufactures. At Sterling Spring we produce 15,000 of these antenna assemblies annually and we deliver to a major communications manufacturer.
