Maybe. Regular heatshrink doesn't do very well outside - it weathers and
stretches - so what you wind up with is weatherproofing that isn't
weatherproof. Some people use it mistakenly thinking it provides
weatherproofing and
it doesn't.
If you use one of the current RF-type heatshrinks, they're quite good.
The rubber is thicker and more resistant to UV plus the glue inside melts and
really holds it on the connector. The glue seals it pretty well against
water incursion. It's really good stuff and not inexpensive.
