If you plan to cut the cable and add a roof antenna then i HIGHLY recommend replacing all Cable lines with this product. I have four 25ft long runs coming from a 4-way splitter and 50ft of this cable from the roof antenna to the 4-way and I get excellent pictures on all four TVs. But you have to replace the old cable wiring. Make sure you buy the Quad shield version. Cost twice as much. But worth it.
