Yes, that's why you see them everywhere in professional installations.
I've tried everything else in this wet climate, and cable glands are the
solution that works every time.
The cheap plastic ones are fine, and most of the time you only need two
sizes: small ones for RG58/RG6 etc and a larger size for RG213 and rotor
cable.

It won't give a good seal onto two cables, but a shot of hot melt glue
into each end of the rubber sleeve will fill the gap. Do this with the
sleeve pulled out of the gland and let the glue set. Then assemble the
gland and tighten the nut to compress the sleeve some more.
