• [ ] various mounting brackets and cables.

Will probably need to have these in are possession to get accurate measurements for most of these.**

The cad model has been updated with the folowing

• Added wifi dish mounting option as seen in #12
• altered 70cm antenna representation to match rougth dimensions from #15

• [ ] Diplexer for 2/70cm
• [ ] cable retainers

The folowing need adding further down the building
