Should Rode be on here as Røde? Or Hofner just be Höfner?

It's definitely Höfner. You can write Hoefner as well, if your input device doesn't offer the right typo. The term Hofner was introduced by people who don't understand the German language.

Updated!

Yes hard to say , there will be still English Speakers writing Hofner but its Höfner. That is why I did long time ago Brand it as Hofner (Höfner) here. In German you can do ö = oe , ä = ae , ü = ue , but Not on Names this is just for normal words possible in german grama. On Names is ö or oe possible and you have to take it as its written, people do ask then also: Is your name oe or normal ö.
