SMA or bust. The other three connector types introduce a lot of noise compared to SMA in my experience. BNC is my goto if I want a noise profile similar to SMA but the device I'm working with isn't vibration damped.
Oh dang, I totally missed the name of this community when I commented. My knowledge of and opinions on rf connectors come from working on large aircraft mounted systems, where turbulence can cause a nightmare of threaded connector sleeves vibrating loose and bent pins. In this situation you either need vibration damping or a more mechanically robust connector like BNC
PL259 has non-constant impedance, which is the main reason I don't like it.
N type is a near perfect connector except huge size, which has constant impedance, supports frequency up to 11GHz, is waterproof and can be used with high power.
SMA is similar to N type but has smaller size and lower power.
U.FL will be the only choice if you only have very tiny space. (The situation never happened in ham radio)

@einfach_orangensaft Furiously agree. PL259 is harder to put on than a decent type N

SMA is too fragile and PL-259 is a pain to weatherproof. I prefer BNC for portable use and N connectors for just about everything else.

That’s interesting as PL-259 is the standard for marine use. I wish we had something better

Where is BNC, and why is uFL here?

Ufl sucks. No mechanical lock.

What's the role of vibration damping? SMA comes on most HTs.

Makes sense, thanks
