The BigIR is ready for assembly. The two white PVC tubes are glued together and to the EHU with the provided glue kit. There is a coupler pre-installed on one of the tubes and another coupler on the EHU.
Those tubes serve to guide the antenna element thru the larger diameter fiber-glass tubes.
In the next step the two fiber-glass extension tubes are slid over the white PVC guide.
Spotty is observing the assembly process making sure that I am not missing something.
