== 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!
