Here are some pictures of the cross dipole array I built from PVC and brazing rods:


Starting assembly of one dipole arm. The PVC joints are not glued until after debugging.


The antenna termination board in the dipole PVC mount.


The cross member assembly is glued to the adapter after drilling through the PVC cross.


One arm complete with the coax threaded through the PVC cross joint.


All four arms assembled, but not glued, and coax ready for Antenna board attachment.


Assembled, not glued, and ready for testing.


Initially the cables were to come out the bottom, but it is just too tight in the base PVC. Later the holes were sealed with silicon calking


Here's the array intstalled for testing on the roof.
