If all else fails cut a disk of thin rubber , inner tube or very thin mat suitably sized to cover the hole and seal it to the coax and round the hole ( leaving a small bottom gap. Roof and gutter silicone is good) foam is effective but tends to wick water so you still need a suitable seal and making your own is much cheaper .

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.
