antenna booster

Thanks for all the posts concerning my booster problem. Pulled it out and checked the 12VDC, it's ok. Was receiving 2 channels with booster off and none with it on. Antenna checked ok, on an after thought, I switched the input cables (cable and antena) at the booster and wala, now have 20 channels with booster on. Problem solved to my satisfaction, thanks again for the inputs.....I love this forum!!!
