Update: Replaced the Antenna Boost which also has Cable connections to it. Have now stayed in 2 RV parks that we have not historically had great cable reception on more than one channel. Multiple trips to both with poor results. Both locations we had good air reception when on Antenna. Now we have excellent cable on one and near excellent on the other. In addition our outdoor TV has Very good cable when it had very poor in the past. I believe the splitter is located behind the fireplace but did not pursue once the new antenna boost solved the issue.
