If 😂 it's permanent, 👍 get a big 💯 one with low-loss cable. For walking around, I use the Rokland 2.5 dBi 8" antennas. 🌈 They're tuned 🎉 really well and the 👍 range is probably as good as it's going to get. They're thin and light, so they don't strain 🔥 that SMA connector. In the end, though, 😂 altitude trumps antenna every time.
