Hello! I've recently set up Freeview on my HTPC, but unfortunately certain family members aren't yet capable of using it and insist on having an aerial plugged into the TV itself so they can use its tuner. Unplugging and replugging every time I want to watch Freeview is quite the chore.

I imagine I need something like this. However, my problem is that my aerial connection is a cable coming straight out of the antenna and terminating in a male jack (which plugs directly into the tuner/TV/whatever), and I have a feeling the input on that splitter is female. My cable is also not F-type (threaded) but rather plain coax.

This should be so simple but is making my head spin. What do I need? What about one of these and one of these? (link may not work due to stupid DSE site).
