Install a smaller DBS antenna over an existing metal pipe with the 2” pipe adapter. When you have smaller antennas, smaller diameter short mounting poles are needed. The 2” pipe adapter can make any stationary, securely mounted steel pipe of practically any kind work. Simply slip the adapter’s slotted end over the exposed open part of the pipe and affix it with the grade 5 hex head bolts that come standard with it. Ideal for use with round pipes as flat steel does not have the necessary grip. Outside diameter of the adapter is 2” and is powder coated grey in color.
