What is the best way to seal up the gaps around coax cable at the building cable entrance port? Our location has a panel with rubber knockouts. Some of the gaps are large. Unfortunately the original contractor that installed the cables did not leave a drip loop and after a heavy rain we get some water in the building. Also the gaps are easy access for bugs and mice.
We have considered using Great Stuff foam insulation but are not sure if this is the thing to do. Suggestions appreciated. Wayne WA5LUY
