Agree. I could be wrong, but I thought the Wboost/Wilson boosters used a different type of coax.N7SHG_Ham said:That does terminate at the outside cable jack. What I don't know is if the coax type is the same or the connectors. You would have to make sure the coax on the booster is of the same impedance as the pre installed TV coax. Your idea may work if everything matches.
