There may be something we are missing here, it is possible that the OP's antenna is non amplified. Easy way to tell is the head and wings would be Grey rather than White and aluminum. A partial answer to the OP's question is here
(Answer) if the OP only has one TV then I think the inline amp would be a good replacement for the broken one if he has two, the more expensive distribution amplifier would be a good choice.
Even though the Sensar Pro would be a great answer, it may not meet the OP's needs. All the money and work to change out is not worth it to me, all I want to watch OTA is the local and national news.
