Though it's not commonly available, there are specialty types of heat shrink with heat activated sealant added to the inside wall of the tube. Given the specialized nature, limited availability and cost of the product, I wouldn't think to suggest it's use in an OTA installation. I would not expect the commonly available HST to provide a reliable seal against water/moisture.

Product such as CoaxSeal and Scotch/3M 2228 would be better suited to sealing F-type connectors.
