,,,by Harry36 user....
For manufacturing, you will need galvanized iron with a thickness of 0.5 mm (no more, this is due to the height of the patch above the reflector), two SMA connectors, an M8 bolt, an M8 nut, an aluminum pipe with a diameter of 8 mm, and foamed PVC.
The design is relatively easy for home production, even a round element of this diameter will not be difficult to cut with metal scissors. Follow all the dimensions and recommendations as accurately as possible and you will have a great antenna. -

,,,yes, but it must be taken into account that for the frequency of 900 MHz, the diameter of the reflector is around 250mm...!!!
