-==== Housing ====
-<bootnote>ToDo GHousing text and data</bootnote> OVI40 will not fit the current mcHF casings. In contrast to the mcHF, the OVI40 RF boards will have additional PCB boards plugged into them. It is assumed that these adapter boards may be up to 5 cm long. There will be OVI40 specific casings developped and provided who do not want to build their own housing. These housings will be developped after the OVI40 has been finished.
