Hi Bob
You need one of these. I've got a couple and they work well - let's me run things from the dining room table just inside.

There's a 5m model too, but 10m has always worked fine for me.
I don't expect to be running a superfast framerate planetary cam or similar mind you, but seems to cope with Mount hub pro controlling QHY9, QHY5II, and EQ6.
