Basically title. I'm in the EU, so I need a 868Mhz one. I need it to be weather-resistant, because I'm making an outdoors node. Cost and size are not an issue. I plan to mount it relatively high.

I'll most likely install it on a Heltec T114.

Don't go any higher than a 5DBI antenna. Otherwise, you'll start to lose signal directly above and below your antenna. A 3 or 5 DBI antenna makes a much more spherical radiation pattern, whereas 8, 10 and 12 make more pancake type radiation patterns.
