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).
