Title should have read... two VHF devices... sorry

This question is not directly related to antennas but the principle is the same.

I have a TV capture card in my computer. It has two tuners and can take a single RF feed (cable or antenna) and record two shows at the same time.

My need is to feed in two RF signals from two cable boxes. One set to Ch4 and the other to Ch3. My question is, what can I use to combine the two RF coax feeds into one to send to the capture card's coax connection?

Thanks for the help on this.
