== 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 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!
