Just pulling together putting this into a case I'll make from FR4 offcuts.
Will add 3 push to make switches an on/off, external DC feed and will add an external SMA.
getting there, bit bigger than just the HP360 but will fit something else in the case too.
Lid (no photo just yet) will be added and the HP360 will screwed into it.
The switches a DC connector I'll fit to the base before hand. The remaining space will probably be taken up with a simple VSWR meter.
