Powerful Features: Antenna mount is great for replacing lost or damaged old pieces. Standard size, 3/8 x 24 thread is ideal for holding 102" antennas and most antennas. Can be used on any mounting surface with 1/2" (13mm) holes, suitable for most vehicles such as jeep trucks, etc. | Ease of Use: Installation takes just a few minutes. Make sure the white insulating washer goes on top of the mount, the stud base from the bottom through it, then the flat washer on top, then the split washer. The antenna has to be isolated from the mounting bracket so make sure it is centered on the plastic washer or it will short out your system. Antenna mounts feature threaded screw-in coaxial terminations for easy removal and installation. | Firmly Connect: Stud mount is strong enough to withstand all the pressure from the antenna without worrying about the antenna swinging and falling. The antenna stud mount acts as a bridge between the antenna and the coaxial feedline. It allows for efficient transfer of your transmitted and received signals to and from the transceiver, guaranteeing a clear and loud signal. | Durable Material: CB radio antenna mount is made of all-copper nickel-plated material to ensure durability, and the excellent material ensures a strong and tight connection, not easy to break. White washer provides good insulation and keeps the antenna from grounding out on your mounting point. | 100% Guarantee: All Ancable products come with our 100% No Questions Asked Guarantee.
