Todo
- Site survey roof, check if there is already some sort of lightning protection system, and see if we can add some metal construction to it ourselfs
- Currently we have no antenna. Well need some heavy duty (directional?) antenna.
- Do we make one or do we buy one?
- What kind of antenna? (keep in mind we only have line of sight towards south/southwest)
- Enclosure spec-en en aanschaffen
- Routing 230v and Ethernet towards the roof
- Your ideas, we love them!
