The standard is compression connectors. These are used by almost everyone
and can be bought almost everywhere, although out of the US, it may be
cheaper to buy them from eBay vendors.

Specialty shops that cater to satellite TV and cable TV installers stock
them worldwide.

There is a varying range of quality, price, watertightness, etc. You can
also get various ones for specific cables and for more generic, e.g.
one connector for all variants of RG-6.

These work by putting the cable in the connector, putting the connector
in a compression tool and squeezing. Most compress a ring on the back
twoard the front, which causes an internal tube to be pressed in, but I
also have some where the front is pushed in.

You can also buy waterproof boots for F connectors to really keep the water
out.

I have not only F connectors, but BNC and RCA too.

Compression connectors are good for indoors, but even the "waterproof
boots" don't do well in situations such as ham antennas. They're OK if
you're connecting to an "F" connector female, but even then they have a
tendency to leak if left in inclement weather for too long.

Ring terminals are good when you don't have a female "F" connector but
terminals (or bolts) instead. But if they are exposed to the weather,
they should be soldered instead of crimped.

We go through a lot of "F" connectors. But we've never found a great
solution for male "F" connectors connected to female "F" connectors and
exposed to the elements. They start to fail after about 5 years or do.

Crimped "F" connectors in protected environments last for decades,
though. Never had a good crimp fail in over 10 years of installations.
