Still can not get any channels on my TV????

OK I did go back to basic. I went on the roof and installed a new cable down through the side window and direct to the original box that was in the MH when I got it. Then I took the cable from the TV straight to the box. I got one TV Chanel. which was not to strong. kept freezing up, but did help. Then I took the MH up to Walmart which is on a steep hill. I got two nice channels. Today here it has rain very hard and have not done any thing with the MH. Tomorrow I will install the Sensor Pro. It had two wires keep coming out. I fix that today. I am doing one steep at a time. I should get 3 channels here and 12 or more up at Walmart at least my old MH did. I did have the same problem when I got it. I did put a booster on it and it made all the difference. BUT I did have a Winegard Sensor Pro. I have not got a Booster yet. Will this a chance. I want to thank you for your help. I do live in a poor area for TV antenna.
