rf modulator grainy

i have directv and the receiver has 2 outputs. hdmi and dtv 10 pin. i got a 10 pin adapter so i can feed 2 tvs and it has red-yel-wht and i feed that into a rf modulator box and than send the co-ax output to the next room but i see that the pic on the newer 20" tv is so-so. i have to use the tuner input and use ch 3 and the pic is kinda grainy and the contrast is poor. the rf mod box is just an impedance/connector type adapter? from rca-co-ax? should i have a good pic on tv or so so?
