Well I finally got some WF100 cable (CT100 replacement) to get a feed from the now unused Astra dish to the shack. My remaining CT125 is about 10 feet long and would get me nowhere. So I can finally test the Minitiouner on air and it works. No luck with trying to receive GB3YT though, it should be close enough and I have a small 23cm Yagi but our neighbours house is in the way. I will have to go mobile one day and see if it works, which is going to be hard given the rather old Windows laptop has a battery that lasts about 5 minutes and the XYLs laptop is locked down to a work image so no installing Minitioune. Anyway, for now at least it all works. It could us a switch maybe to switch the 12V feed to the antenna socket on and off.
Yes it is indeed in a box. This must be the second project I ever built that ended up in an actual decent box looking finished.
