F connectors should stay on your satellite equipment....nowhere else

F connectors, the cheap ones, use coax with a single solid centre conductor. Single solid conductors are deprecated in mobile applications.
Why's that, Jim? They are also the standard connector for cable TV equipment (and have been from long before we ever had satellite). I believe that they first became used on TV sets in the USA when they went away from aerials with 300 ohm twin feeder. They are pretty good (and very cheap) connectors.
Why's that?
They snap when subjected to vibration
Their great point is that they avoid the unsoldered Belling Lee connector.
a solid conductor is more prone to breaking than a multistranded one.
If the level of vibration in your car is sufficient to snap coax cable, maybe it's about time to think about getting a new one!
Solid core cable isn't allowed on new-build boats for the same reason
ok also on my Kenpro KP202 as well then...and the holy virgin....I suppose using the coax inner as the centre pin is cool no soldering....I take it back...
that's you told Ian....tee hee
no I don't the vibration on my KP202 caused the sold centre core to snap....tee hee

Tiny, specialised connectors make sense when you're using small-diameter cable. F-connectors are ideal for situations where the inner conductor is the pin of the male - and you obviously can't do this with miniature cable. If you ARE using miniature cable, you'll need to use a different type of F-connector (probably more expensive) - one which has its own pin (and, of course, the cable can be multistrand).
nice comeback
I've actually got some jumpers using miniature cable (RG-179?) and F-connectors. You have to solder the inner into the pin, and crimp* the outer.
*If the dielectric is high-temperature, you can also solder the folded-back outer braid.
oh right
And lead-free solder is banned on critical aircraft wiring
My Onkyo CR515DAB mini hifi had a male belling lee? FM socket which was a nuisance when I first bought it and tried to set it up at 7PM one evening.
should be totally banned then there would be less chinky junk to throw away .....
