Ignacy,
You definitely do not want any water, or moisture, to leak into any coax cable,
even if it just effects the outer shield(s), and thus likely the connector as
well. This is why some connectors have water seals in them. But regardless of
seals, for outdoor installations, it is always a procedure by commercial and
military to seal over the coax and up and over the connector, with adequate
sealing material, that is also UV resistant. Or, if using one of the many
sealing materials, if not UV resistant, then with UV resistant tape over it.
If you search the archives here, you will likely find a lot of recommendations
for connector sealing material and UV resistant tape.

How important is cable quality to avoid leaks? Some cables have more
braiding and some less. Some have an aluminum foil and some don't. If a
cable checks well for loss and impedance, is it likely to be good enough?
So far, all detectable leaks at my station were due to loose connectors not
cables. But I am planning SO2R and then even low level leaks may be
noticeable.
