| − | * 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 send and receive with just some breadboard cables. Works fine in the lab but we need some heavy duty antenna outside.
| |
| − | ** 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!
