BNC looms large and RULES!

@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?

[–] LH0ezVT@sh.itjust.works 3 points 1 year ago

Ufl sucks. No mechanical lock.

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.

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

[–] Gustephan@lemmy.world 4 points 1 year ago (1 children)

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

Makes sense, thanks

UC-1 are less fragile than the petite SMAs

[–] Coelacanthus@lemmy.kde.social 1 points 10 months ago

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)
