If you do not want to buy any extra hardware, just connect the antenna cable from the wall to the VHS antenna in, and then connect from VHS antenna out to DVD recorder antenna in, and then from DVD record antenna out to TV antenna in. But the reception of signal will be degraded from one to another. So if you want a better reception, you can buy a TV signal amplifier which also have two or three antenna output. This kind of amplifier costs you less than $100.
